+Subject: afs: Fix infinite loop found by xfstest generic/676
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 17eabd42560f4636648ad65ba5b20228071e2363 ]
+
+In AFS, a directory is handled as a file that the client downloads and
+parses locally for the purposes of performing lookup and getdents
+operations. The in-kernel afs filesystem has a number of functions that
+do this.
+
+A directory file is arranged as a series of 2K blocks divided into
+32-byte slots, where a directory entry occupies one or more slots, plus
+each block starts with one or more metadata blocks.
+
+When parsing a block, if the last slots are occupied by a dirent that
+occupies more than a single slot and the file position points at a slot
+that's not the initial one, the logic in afs_dir_iterate_block() that
+skips over it won't advance the file pointer to the end of it. This
+will cause an infinite loop in getdents() as it will keep retrying that
+block and failing to advance beyond the final entry.
+
+Fix this by advancing the file pointer if the next entry will be beyond
+it when we skip a block.
+
+This was found by the generic/676 xfstest but can also be triggered with
+something like:
+
+ ~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

+
+[ Upstream commit 4d338ee40ba89e508c5d3e1b4af956af7cb5e12e ]
+
+Since mac0/1 and mac2/3 are physically located on different die,
+they have different properties by nature, which is mac0/1 has smaller delay step.
+
+The property 'phy-mode' on ast2600 mac0 and mac1 is recommended to set to 'rgmii-rxid'

+Subject: ax25: Fix ax25 session cleanup problems
+
+From: Duoming Zhou <duoming@zju.edu.cn>
+
+[ Upstream commit 7d8a3a477b3e25ada8dc71d22048c2ea417209a0 ]
+
+There are session cleanup problems in ax25_release() and
+ax25_disconnect(). If we setup a session and then disconnect,
+the disconnected session is still in "LISTENING" state that
+is shown below.
+
+Active AX.25 sockets
+Dest Source Device State Vr/Vs Send-Q Recv-Q
+DL9SAU-4 DL9SAU-3 ??? LISTENING 000/000 0 0
+DL9SAU-3 DL9SAU-4 ??? LISTENING 000/000 0 0
+
+The first reason is caused by del_timer_sync() in ax25_release().
+The timers of ax25 are used for correct session cleanup. If we use
+ax25_release() to close ax25 sessions and ax25_dev is not null,
+the del_timer_sync() functions in ax25_release() will execute.
+As a result, the sessions could not be cleaned up correctly,
+because the timers have stopped.
+
+In order to solve this problem, this patch adds a device_up flag
+in ax25_dev in order to judge whether the device is up. If there
+are sessions to be cleaned up, the del_timer_sync() in
+ax25_release() will not execute. What's more, we add ax25_cb_del()
+in ax25_kill_by_device(), because the timers have been stopped
+and there are no functions that could delete ax25_cb if we do not
+call ax25_release(). Finally, we reorder the position of
+ax25_list_lock in ax25_cb_del() in order to synchronize among
+different functions that call ax25_cb_del().
+
+The second reason is caused by improper check in ax25_disconnect().
+The incoming ax25 sessions which ax25->sk is null will close
+heartbeat timer, because the check "if(!ax25->sk || ..)" is
+satisfied. As a result, the session could not be cleaned up properly.
+
+In order to solve this problem, this patch changes the improper
+check to "if(ax25->sk && ..)" in ax25_disconnect().
+
+What`s more, the ax25_disconnect() may be called twice, which is
+not necessary. For example, ax25_kill_by_device() calls
+ax25_disconnect() and sets ax25->state to AX25_STATE_0, but
+ax25_release() calls ax25_disconnect() again.
+
+In order to solve this problem, this patch add a check in
+ax25_release(). If the flag of ax25->sk equals to SOCK_DEAD,
+the ax25_disconnect() in ax25_release() should not be executed.

+
+Flush or passthrough requests are not accounted as normal IO in completion.
+To reflect iostat for slow IO, io_ticks is updated when stat show called
+based on inflight numbers.
+It may cause inconsistent io_ticks calculation result.

+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 5d05426e2d5fd7df8afc866b78c36b37b00188b7 ]
+
+blk_mq_run_hw_queues() could be run when there isn't queued request and
+after queue is cleaned up, at that time tagset is freed, because tagset
+lifetime is covered by driver, and often freed after blk_cleanup_queue()
+returns.
+
+So don't touch ->tagset for figuring out current default hctx by the mapping
+built in request queue, so use-after-free on tagset can be avoided. Meantime
+this way should be fast than retrieving mapping from tagset.

+From: Jens Axboe <axboe@kernel.dk>
+
+[ Upstream commit 605f7415ecfb426610195dd6c7577b30592b3369 ]
+
+Most of bioset_exit() is fine being called twice, as it clears the
+various allocations etc when they are freed. The exception is
+bio_alloc_cache_destroy(), which does not clear ->cache when it has
+freed it.
+
+This isn't necessarily a bug, but can be if buggy users does call the
+exit path more then once, or with just a memset() bioset which has
+never been initialized. dm appears to be one such user.

+Subject: bluetooth: don't use bitmaps for random flag accesses
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+[ Upstream commit e1cff7002b716bd0b5f5f4afd4273c99aa8644be ]
+
+The bluetooth code uses our bitmap infrastructure for the two bits (!)
+of connection setup flags, and in the process causes odd problems when
+it converts between a bitmap and just the regular values of said bits.
+
+It's completely pointless to do things like bitmap_to_arr32() to convert
+a bitmap into a u32. It shoudln't have been a bitmap in the first
+place. The reason to use bitmaps is if you have arbitrary number of
+bits you want to manage (not two!), or if you rely on the atomicity
+guarantees of the bitmap setting and clearing.
+
+The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
+clear the bit values, but considering that it then copies the bitmaps
+around with "bitmap_to_arr32()" and friends, there clearly cannot be a
+lot of atomicity requirements.
+
+So just use a regular integer.
+
+In the process, this avoids the warnings about erroneous use of
+bitmap_from_u64() which were triggered on 32-bit architectures when
+conversion from a u64 would access two words (and, surprise, surprise,
+only one word is needed - and indeed overkill - for a 2-bit bitmap).
+
+That was always problematic, but the compiler seems to notice it and
+warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
+bitmap_{from,to}_arr64") changed the exact implementation details of
+'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

+Subject: Bluetooth: hci_sync: Fix attempting to suspend with unfiltered
+ passive scan
+
+From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
+
+[ Upstream commit 3b42055388c30f2761a2d9cd9af2c99611dfe457 ]
+
+When suspending the passive scanning _must_ have its filter_policy set
+to 0x01 to use the accept list otherwise _any_ advertise report would
+end up waking up the system.
+
+In order to fix the filter_policy the code now checks for
+hdev->suspended && HCI_CONN_FLAG_REMOTE_WAKEUP
+first, since the MGMT_OP_SET_DEVICE_FLAGS will reject any attempt to
+set HCI_CONN_FLAG_REMOTE_WAKEUP when it cannot be programmed in the
+acceptlist, so it can return success causing the proper filter_policy
+to be used.

+Subject: bpf: Fix probe read error in ___bpf_prog_run()
+
+From: Menglong Dong <imagedong@tencent.com>
+
+[ Upstream commit caff1fa4118cec4dfd4336521ebd22a6408a1e3e ]
+
+I think there is something wrong with BPF_PROBE_MEM in ___bpf_prog_run()
+in big-endian machine. Let's make a test and see what will happen if we
+want to load a 'u16' with BPF_PROBE_MEM.
+
+Let's make the src value '0x0001', the value of dest register will become
+0x0001000000000000, as the value will be loaded to the first 2 byte of
+DST with following code:
+
+ bpf_probe_read_kernel(&DST, SIZE, (const void *)(long) (SRC + insn->off));
+
+Obviously, the value in DST is not correct. In fact, we can compare
+BPF_PROBE_MEM with LDX_MEM_H:
+
+ DST = *(SIZE *)(unsigned long) (SRC + insn->off);
+
+If the memory load is done by LDX_MEM_H, the value in DST will be 0x1 now.
+
+And I think this error results in the test case 'test_bpf_sk_storage_map'
+failing:
+
+ test_bpf_sk_storage_map:PASS:bpf_iter_bpf_sk_storage_map__open_and_load 0 nsec
+ test_bpf_sk_storage_map:PASS:socket 0 nsec
+ test_bpf_sk_storage_map:PASS:map_update 0 nsec
+ test_bpf_sk_storage_map:PASS:socket 0 nsec
+ test_bpf_sk_storage_map:PASS:map_update 0 nsec
+ test_bpf_sk_storage_map:PASS:socket 0 nsec
+ test_bpf_sk_storage_map:PASS:map_update 0 nsec
+ test_bpf_sk_storage_map:PASS:attach_iter 0 nsec
+ test_bpf_sk_storage_map:PASS:create_iter 0 nsec
+ test_bpf_sk_storage_map:PASS:read 0 nsec
+ test_bpf_sk_storage_map:FAIL:ipv6_sk_count got 0 expected 3
+ $10/26 bpf_iter/bpf_sk_storage_map:FAIL
+
+The code of the test case is simply, it will load sk->sk_family to the
+register with BPF_PROBE_MEM and check if it is AF_INET6. With this patch,
+now the test case 'bpf_iter' can pass:
+
+ $10 bpf_iter:OK

+We can get "failed to disable" clock_unprepare warnings on unbind at least

+Subject: coresight: cpu-debug: Replace mutex with mutex_trylock on panic
+ notifier
+
+From: Guilherme G. Piccoli <gpiccoli@igalia.com>
+
+[ Upstream commit 1adff542d67a2ed1120955cb219bfff8a9c53f59 ]
+
+The panic notifier infrastructure executes registered callbacks when
+a panic event happens - such callbacks are executed in atomic context,
+with interrupts and preemption disabled in the running CPU and all other
+CPUs disabled. That said, mutexes in such context are not a good idea.
+
+This patch replaces a regular mutex with a mutex_trylock safer approach;
+given the nature of the mutex used in the driver, it should be pretty
+uncommon being unable to acquire such mutex in the panic path, hence
+no functional change should be observed (and if it is, that would be
+likely a deadlock with the regular mutex).

+Subject: driver core: fix deadlock in __device_attach
+
+From: Zhang Wensheng <zhangwensheng5@huawei.com>
+
+[ Upstream commit b232b02bf3c205b13a26dcec08e53baddd8e59ed ]
+
+In __device_attach function, The lock holding logic is as follows:
+...
+__device_attach
+device_lock(dev) // get lock dev
+ async_schedule_dev(__device_attach_async_helper, dev); // func
+ async_schedule_node
+ async_schedule_node_domain(func)
+ entry = kzalloc(sizeof(struct async_entry), GFP_ATOMIC);
+ /* when fail or work limit, sync to execute func, but
+ __device_attach_async_helper will get lock dev as
+ well, which will lead to A-A deadlock. */
+ if (!entry || atomic_read(&entry_count) > MAX_WORK) {
+ func;
+ else
+ queue_work_node(node, system_unbound_wq, &entry->work)
+ device_unlock(dev)
+
+As shown above, when it is allowed to do async probes, because of
+out of memory or work limit, async work is not allowed, to do
+sync execute instead. it will lead to A-A deadlock because of
+__device_attach_async_helper getting lock dev.
+
+To fix the deadlock, move the async_schedule_dev outside device_lock,
+as we can see, in async_schedule_node_domain, the parameter of
+queue_work_node is system_unbound_wq, so it can accept concurrent
+operations. which will also not change the code logic, and will
+not lead to deadlock.

+Subject: driver core: Fix wait_for_device_probe() & deferred_probe_timeout
+ interaction
+
+From: Saravana Kannan <saravanak@google.com>
+
+[ Upstream commit 5ee76c256e928455212ab759c51d198fedbe7523 ]
+
+Mounting NFS rootfs was timing out when deferred_probe_timeout was
+non-zero [1]. This was because ip_auto_config() initcall times out
+waiting for the network interfaces to show up when
+deferred_probe_timeout was non-zero. While ip_auto_config() calls
+wait_for_device_probe() to make sure any currently running deferred
+probe work or asynchronous probe finishes, that wasn't sufficient to
+account for devices being deferred until deferred_probe_timeout.
+
+Commit 35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits
+until the deferred_probe_timeout fires") tried to fix that by making
+sure wait_for_device_probe() waits for deferred_probe_timeout to expire
+before returning.
+
+However, if wait_for_device_probe() is called from the kernel_init()
+context:
+
+- Before deferred_probe_initcall() [2], it causes the boot process to
+ hang due to a deadlock.
+
+- After deferred_probe_initcall() [3], it blocks kernel_init() from
+ continuing till deferred_probe_timeout expires and beats the point of
+ deferred_probe_timeout that's trying to wait for userspace to load
+ modules.
+
+Neither of this is good. So revert the changes to
+wait_for_device_probe().

+Subject: drm/msm/dp: Always clear mask bits to disable interrupts at
+ dp_ctrl_reset_irq_ctrl()
+
+From: Kuogee Hsieh <quic_khsieh@quicinc.com>
+
+[ Upstream commit 993a2adc6e2e94a0a7b5bfc054eda90ac95f62c3 ]
+
+dp_catalog_ctrl_reset() will software reset DP controller. But it will
+not reset programmable registers to default value. DP driver still have
+to clear mask bits to interrupt status registers to disable interrupts
+after software reset of controller.
+
+At current implementation, dp_ctrl_reset_irq_ctrl() will software reset dp
+controller but did not call dp_catalog_ctrl_enable_irq(false) to clear hpd
+related interrupt mask bits to disable hpd related interrupts due to it
+mistakenly think hpd related interrupt mask bits will be cleared by software
+reset of dp controller automatically. This mistake may cause system to crash
+during suspending procedure due to unexpected irq fired and trigger event
+thread to access dp controller registers with controller clocks are disabled.
+
+This patch fixes system crash during suspending problem by removing "enable"
+flag condition checking at dp_ctrl_reset_irq_ctrl() so that hpd related
+interrupt mask bits are cleared to prevent unexpected from happening.

+Commit ca23ecfdbd44 ("remoteproc/mediatek: support L1TCM") added support
+for the l1tcm memory region on the MT8192 SCP, adding a new da_to_va
+callback that handles l1tcm while keeping the old one for

+missing from the dt-binding, the accompanying dt-binding commit
+503c64cc42f1 ("dt-bindings: remoteproc: mediatek: add L1TCM memory region")
+mistakenly added this reg as if it were for mt8183. And later
+it became common to all platforms as their compatibles were added.
+
+Fix the dt-binding so that the l1tcm reg can be present only on the
+supported platforms: mt8192 and mt8195.

+From: Xiaomeng Tong <xiam0nd.tong@gmail.com>
+
+[ Upstream commit 5a0793ac66ac0e254d292f129a4d6c526f9f2aff ]
+
+The bug is here:
+ pmem->vaddr = NULL;
+
+The list iterator 'pmem' will point to a bogus position containing
+HEAD if the list is empty or no element is found. This case must
+be checked before any use of the iterator, otherwise it will
+lead to a invalid memory access.
+
+To fix this bug, just gen_pool_free/set NULL/list_del() and return
+when found, otherwise list_del HEAD and return;

+
+From: Xin Xiong <xiongx18@fudan.edu.cn>
+
+[ Upstream commit d21a580dafc69aa04f46e6099616146a536b0724 ]
+
+The issue happens in a specific path in smb_check_perm_dacl(). When
+"id" and "uid" have the same value, the function simply jumps out of
+the loop without decrementing the reference count of the object
+"posix_acls", which is increased by get_acl() earlier. This may
+result in memory leaks.
+
+Fix it by decreasing the reference count of "posix_acls" before
+jumping to label "check_access_bits".

+
+[ Upstream commit 4a9800c81d2f34afb66b4b42e0330ae8298019a2 ]
+
+As the possible failure of the kmalloc(), the not_checked and checked
+could be NULL pointer.
+Therefore, it should be better to check it in order to avoid the
+dereference of the NULL pointer.
+Also, we need to kfree the 'not_checked' and 'checked' to avoid
+the memory leak if fails.
+And since it is just a test, it may directly return without error
+number.

+Subject: misc: fastrpc: fix an incorrect NULL check on list iterator
+
+From: Xiaomeng Tong <xiam0nd.tong@gmail.com>
+
+[ Upstream commit 5ac11fe03a0a83042d1a040dbce4fa2fb5521e23 ]
+
+The bug is here:
+ if (!buf) {
+
+The list iterator value 'buf' will *always* be set and non-NULL
+by list_for_each_entry(), so it is incorrect to assume that the
+iterator value will be NULL if the list is empty (in this case, the
+check 'if (!buf) {' will always be false and never exit expectly).
+
+To fix the bug, use a new variable 'iter' as the list iterator,
+while use the original variable 'buf' as a dedicated pointer to
+point to the found element.

+Subject: misc/pvpanic: Convert regular spinlock into trylock on panic path
+
+From: Guilherme G. Piccoli <gpiccoli@igalia.com>
+
+[ Upstream commit e918c10265ef2bc82ce8a6fed6d8123d09ec1db3 ]
+
+The pvpanic driver relies on panic notifiers to execute a callback
+on panic event. Such function is executed in atomic context - the
+panic function disables local IRQs, preemption and all other CPUs
+that aren't running the panic code.
+
+With that said, it's dangerous to use regular spinlocks in such path,
+as introduced by commit b3c0f8774668 ("misc/pvpanic: probe multiple instances").
+This patch fixes that by replacing regular spinlocks with the trylock
+safer approach.
+
+It also fixes an old comment (about a long gone framebuffer code) and
+the notifier priority - we should execute hypervisor notifiers early,
+deferring this way the panic action to the hypervisor, as expected by
+the users that are setting up pvpanic.

+Subject: modpost: fix removing numeric suffixes
+
+From: Alexander Lobakin <alexandr.lobakin@intel.com>
+
+[ Upstream commit b5beffa20d83c4e15306c991ffd00de0d8628338 ]
+
+With the `-z unique-symbol` linker flag or any similar mechanism,
+it is possible to trigger the following:
+
+ERROR: modpost: "param_set_uint.0" [vmlinux] is a static EXPORT_SYMBOL
+
+The reason is that for now the condition from remove_dot():
+
+if (m && (s[n + m] == '.' || s[n + m] == 0))
+
+which was designed to test if it's a dot or a '\0' after the suffix
+is never satisfied.
+This is due to that `s[n + m]` always points to the last digit of a
+numeric suffix, not on the symbol next to it (from a custom debug
+print added to modpost):
+
+param_set_uint.0, s[n + m] is '0', s[n + m + 1] is '\0'
+
+So it's off-by-one and was like that since 2014.
+
+Fix this for the sake of any potential upcoming features, but don't
+bother stable-backporting, as it's well hidden -- apart from that
+LD flag, it can be triggered only with GCC LTO which never landed
+upstream.

+Subject: net: lan966x: check devm_of_phy_get() for -EDEFER_PROBE
+
+From: Michael Walle <michael@walle.cc>
+
+[ Upstream commit b58cdd4388b1d8f5bee9f5a3897a7e780d1eaa48 ]
+
+At the moment, if devm_of_phy_get() returns an error the serdes
+simply isn't set. While it is bad to ignore an error in general, there
+is a particular bug that network isn't working if the serdes driver is
+compiled as a module. In that case, devm_of_phy_get() returns
+-EDEFER_PROBE and the error is silently ignored.
+
+The serdes is optional, it is not there if the port is using RGMII, in
+which case devm_of_phy_get() returns -ENODEV. Rearrange the error
+handling so that -ENODEV will be handled but other error codes will
+abort the probing.

+
+From: Paul Blakey <paulb@nvidia.com>
+
+[ Upstream commit 1f2856cde64baa78475e6d3c601fb7b7f693a161 ]
+
+Tuple entries that don't have nat configured for them
+which are added to the ct nat table will always create
+a new modify header, as we don't check for possible
+re-use on them. The same for tuples that have nat configured
+for them but are added to ct table.
+
+Fix the above by only avoiding wasteful re-use lookup
+for actually natted entries in ct nat table.

+Subject: net/mlx5e: Disable softirq in mlx5e_activate_rq to avoid race
+ condition
+
+From: Maxim Mikityanskiy <maximmi@nvidia.com>
+
+[ Upstream commit 2e642afb61b24401a7ec819d27ddcd69c7c29784 ]
+
+When the driver activates the channels, it assumes NAPI isn't running
+yet. mlx5e_activate_rq posts a NOP WQE to ICOSQ to trigger a hardware
+interrupt and start NAPI, which will run mlx5e_alloc_rx_mpwqe and post
+UMR WQEs to ICOSQ to be able to receive packets with striding RQ.
+
+Unfortunately, a race condition is possible if NAPI is triggered by
+something else (for example, TX) at a bad timing, before
+mlx5e_activate_rq finishes. In this case, mlx5e_alloc_rx_mpwqe may post
+UMR WQEs to ICOSQ, and with the bad timing, the wqe_info of the first
+UMR may be overwritten by the wqe_info of the NOP posted by
+mlx5e_activate_rq.
+
+The consequence is that icosq->db.wqe_info[0].num_wqebbs will be changed
+from MLX5E_UMR_WQEBBS to 1, disrupting the integrity of the array-based
+linked list in wqe_info[]. mlx5e_poll_ico_cq will hang in an infinite
+loop after processing wqe_info[0], because after the corruption, the
+next item to be processed will be wqe_info[1], which is filled with
+zeros, and `sqcc += wi->num_wqebbs` will never move further.
+
+This commit fixes this race condition by using async_icosq to post the
+NOP and trigger the interrupt. async_icosq is always protected with a
+spinlock, eliminating the race condition.

+highest priority in the NIC table replacing the vlan table, this caused
+tc NIC tables miss flow to skip the prmoisc table because it use vlan
+table as miss table.
+
+OVS offload in NIC mode use promisc by default so any unicast packet
+which will be handled by tc NIC tables miss flow will skip the promisc
+rule and will be dropped.
+
+Fix this by adding new empty table in new tc level with low priority and
+point the nic tc chain miss to it, the new table is managed so it will
+point to vlan table if promisc is disabled and to promisc table if enabled.

+Subject: net/mlx5e: Update netdev features after changing XDP state
+
+From: Maxim Mikityanskiy <maximmi@nvidia.com>
+
+[ Upstream commit f6279f113ad593971999c877eb69dc3d36a75894 ]
+
+Some features (LRO, HW GRO) conflict with XDP. If there is an attempt to
+enable such features while XDP is active, they will be set to `off
+[requested on]`. In order to activate these features after XDP is turned
+off, the driver needs to call netdev_update_features(). This commit adds
+this missing call after XDP state changes.

+Subject: net: sched: add barrier to fix packet stuck problem for lockless
+ qdisc
+
+From: Guoju Fang <gjfang@linux.alibaba.com>
+
+[ Upstream commit 2e8728c955ce0624b958eee6e030a37aca3a5d86 ]
+
+In qdisc_run_end(), the spin_unlock() only has store-release semantic,
+which guarantees all earlier memory access are visible before it. But
+the subsequent test_bit() has no barrier semantics so may be reordered
+ahead of the spin_unlock(). The store-load reordering may cause a packet
+stuck problem.
+
+The concurrent operations can be described as below,
+ CPU 0 | CPU 1
+ qdisc_run_end() | qdisc_run_begin()
+ . | .
+ ----> /* may be reorderd here */ | .
+| . | .
+| spin_unlock() | set_bit()
+| . | smp_mb__after_atomic()
+ ---- test_bit() | spin_trylock()
+ . | .
+
+Consider the following sequence of events:
+ CPU 0 reorder test_bit() ahead and see MISSED = 0
+ CPU 1 calls set_bit()
+ CPU 1 calls spin_trylock() and return fail
+ CPU 0 executes spin_unlock()
+
+At the end of the sequence, CPU 0 calls spin_unlock() and does nothing
+because it see MISSED = 0. The skb on CPU 1 has beed enqueued but no one
+take it, until the next cpu pushing to the qdisc (if ever ...) will
+notice and dequeue it.
+
+This patch fix this by adding one explicit barrier. As spin_unlock() and
+test_bit() ordering is a store-load ordering, a full memory barrier
+smp_mb() is needed here.

+Subject: net: sched: fixed barrier to prevent skbuff sticking in qdisc backlog
+
+From: Vincent Ray <vray@kalrayinc.com>
+
+[ Upstream commit a54ce3703613e41fe1d98060b62ec09a3984dc28 ]
+
+In qdisc_run_begin(), smp_mb__before_atomic() used before test_bit()
+does not provide any ordering guarantee as test_bit() is not an atomic
+operation. This, added to the fact that the spin_trylock() call at
+the beginning of qdisc_run_begin() does not guarantee acquire
+semantics if it does not grab the lock, makes it possible for the
+following statement :
+
+if (test_bit(__QDISC_STATE_MISSED, &qdisc->state))
+
+to be executed before an enqueue operation called before
+qdisc_run_begin().
+
+As a result the following race can happen :
+
+ CPU 1 CPU 2
+
+ qdisc_run_begin() qdisc_run_begin() /* true */
+ set(MISSED) .
+ /* returns false */ .
+ . /* sees MISSED = 1 */
+ . /* so qdisc not empty */
+ . __qdisc_run()
+ . .
+ . pfifo_fast_dequeue()
+ ----> /* may be done here */ .
+| . clear(MISSED)
+| . .
+| . smp_mb __after_atomic();
+| . .
+| . /* recheck the queue */
+| . /* nothing => exit */
+| enqueue(skb1)
+| .
+| qdisc_run_begin()
+| .
+| spin_trylock() /* fail */
+| .
+| smp_mb__before_atomic() /* not enough */
+| .
+ ---- if (test_bit(MISSED))
+ return false; /* exit */
+
+In the above scenario, CPU 1 and CPU 2 both try to grab the
+qdisc->seqlock at the same time. Only CPU 2 succeeds and enters the
+bypass code path, where it emits its skb then calls __qdisc_run().
+
+CPU1 fails, sets MISSED and goes down the traditionnal enqueue() +
+dequeue() code path. But when executing qdisc_run_begin() for the
+second time, after enqueuing its skbuff, it sees the MISSED bit still
+set (by itself) and consequently chooses to exit early without setting
+it again nor trying to grab the spinlock again.
+
+Meanwhile CPU2 has seen MISSED = 1, cleared it, checked the queue
+and found it empty, so it returned.
+
+At the end of the sequence, we end up with skb1 enqueued in the
+backlog, both CPUs out of __dev_xmit_skb(), the MISSED bit not set,
+and no __netif_schedule() called made. skb1 will now linger in the
+qdisc until somebody later performs a full __qdisc_run(). Associated
+to the bypass capacity of the qdisc, and the ability of the TCP layer
+to avoid resending packets which it knows are still in the qdisc, this
+can lead to serious traffic "holes" in a TCP connection.
+
+We fix this by replacing the smp_mb__before_atomic() / test_bit() /
+set_bit() / smp_mb__after_atomic() sequence inside qdisc_run_begin()
+by a single test_and_set_bit() call, which is more concise and
+enforces the needed memory barriers.

+When the MIPS_ALCHEMY board selection is MIPS_XXS1500 instead of
+MIPS_DB1XXX, the PCMCIA driver 'db1xxx_ss' has build errors due

+A hybrid platform has a different PMU name for the core PMUs, while
+the current perf hard code the PMU name "cpu".
+
+The evsel->pmu_name can be used to replace the "cpu" to fix the issue.
+For a hybrid platform, the pmu_name must be non-NULL. Because there are
+at least two core PMUs. The PMU has to be specified.
+For a non-hybrid platform, the pmu_name may be NULL. Because there is
+only one core PMU, "cpu". For a NULL pmu_name, we can safely assume that
+it is a "cpu" PMU.
+
+In case other PMUs also define the "slots" event, checking the PMU type
+as well.

+Subject: perf record: Support sample-read topdown metric group for hybrid
+ platforms
+
+From: Zhengjun Xing <zhengjun.xing@linux.intel.com>
+
+[ Upstream commit 151e7d75036b4e2ac0f33730bc1a5b3ff424d9a7 ]
+
+With the hardware TopDown metrics feature, the sample-read feature should
+be supported for a TopDown group, e.g., sample a non-topdown event and read
+a Topdown metric group. But the current perf record code errors are out.
+
+For a TopDown metric group,the slots event must be the leader of the group,
+but the leader slots event doesn't support sampling. To support sample-read
+the TopDown metric group, uses the 2nd event of the group as the "leader"
+for the purposes of sampling.
+
+Only the platform with the TopDown metric feature supports sample-read the
+topdown group. In commit acb65150a47c ("perf record: Support sample-read
+topdown metric group"), it adds arch_topdown_sample_read() to indicate
+whether the TopDown group supports sample-read, it should only work on the
+non-hybrid systems, this patch extends the support for hybrid platforms.

+Subject: phy: rockchip-inno-usb2: Fix muxed interrupt support
+
+From: Samuel Holland <samuel@sholland.org>
+
+[ Upstream commit 6a98df08ccd55e87947d253b19925691763e755c ]
+
+This commit fixes two issues with the muxed interrupt handler. First,
+the OTG port has the "bvalid" interrupt enabled, not "linestate". Since
+only the linestate interrupt was handled, and not the bvalid interrupt,
+plugging in a cable to the OTG port caused an interrupt storm.
+
+Second, the return values from the individual port IRQ handlers need to
+be OR-ed together. Otherwise, the lack of an interrupt from the last
+port would cause the handler to erroneously return IRQ_NONE.

+From: Sergey Shtylyov <s.shtylyov@omp.ru>
+
+[ Upstream commit ce753ad1549cbe9ccaea4c06a1f5fa47432c8289 ]
+
+The commit a85a6c86c25b ("driver core: platform: Clarify that IRQ 0 is
+invalid") only calls WARN() when IRQ0 is about to be returned, however
+using IRQ0 is considered invalid (according to Linus) outside the arch/
+code where it's used by the i8253 drivers. Many driver subsystems treat
+0 specially (e.g. as an indication of the polling mode by libata), so
+the users of platform_get_irq[_byname]() in them would have to filter
+out IRQ0 explicitly and this (quite obviously) doesn't scale...
+Let's finally get this straight and return -EINVAL instead of IRQ0!

+
+[ Upstream commit bd52cd5e23f134019b23f0c389db0f9a436e4576 ]
+
+The argument of scatterwalk_unmap() is supposed to be the void* that was
+returned by the previous scatterwalk_map() call.
+The s390 AES-GCM implementation was instead passing the pointer to the
+struct scatter_walk.
+
+This doesn't actually break anything because scatterwalk_unmap() only uses
+its argument under CONFIG_HIGHMEM and ARCH_HAS_FLUSH_ON_KUNMAP.

+Subject: s390/mcck: isolate SIE instruction when setting CIF_MCCK_GUEST flag
+
+From: Alexander Gordeev <agordeev@linux.ibm.com>
+
+[ Upstream commit 29ccaa4b35ea874ddd50518e5c2c746b9238a792 ]
+
+Commit d768bd892fc8 ("s390: add options to change branch prediction
+behaviour for the kernel") introduced .Lsie_exit label - supposedly
+to fence off SIE instruction. However, the corresponding address
+range length .Lsie_crit_mcck_length was not updated, which led to
+BPON code potentionally marked with CIF_MCCK_GUEST flag.
+
+Both .Lsie_exit and .Lsie_crit_mcck_length were removed with commit
+0b0ed657fe00 ("s390: remove critical section cleanup from entry.S"),
+but the issue persisted - currently BPOFF and BPENTER macros might
+get wrongly considered by the machine check handler as a guest.

+Subject: scsi: sd: Fix potential NULL pointer dereference
+
+From: Damien Le Moal <damien.lemoal@opensource.wdc.com>
+
+[ Upstream commit 05fbde3a77a4f1d62e4c4428f384288c1f1a0be5 ]
+
+If sd_probe() sees an early error before sdkp->device is initialized,
+sd_zbc_release_disk() is called. This causes a NULL pointer dereference
+when sd_is_zoned() is called inside that function. Avoid this by removing
+the call to sd_zbc_release_disk() in sd_probe() error path.
+
+This change is safe and does not result in zone information memory leakage
+because the zone information for a zoned disk is allocated only when
+sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set,
+resulting in sd_disk_release() being called when needed to cleanup a disk
+zone information using sd_zbc_release_disk().

+MIME-Version: 1.0

+
+[ Upstream commit af0179270977508df6986b51242825d7edd59caf ]
+
+SER_RS485_RTS_ON_SEND and SER_RS485_RTS_AFTER_SEND relate to behavior
+within RS485 operation. The driver checks if they have the same value
+which is not possible to realize with the hardware. The check is taken
+regardless of SER_RS485_ENABLED flag and -EINVAL is returned when the
+check fails, which creates problems.
+
+This check makes it unnecessarily complicated to turn RS485 mode off as
+simple zeroed serial_rs485 struct will trigger that equal values check.
+In addition, the driver itself memsets its rs485 structure to zero when
+RS485 is disabled but if userspace would try to make an TIOCSRS485
+ioctl() call with the very same struct, it would end up failing with
+-EINVAL which doesn't make much sense.
+
+Resolve the problem by moving the check inside SER_RS485_ENABLED block.

+Subject: serial: meson: acquire port->lock in startup()
+
+From: John Ogness <john.ogness@linutronix.de>
+
+[ Upstream commit 589f892ac8ef244e47c5a00ffd8605daa1eaef8e ]
+
+The uart_ops startup() callback is called without interrupts
+disabled and without port->lock locked, relatively late during the
+boot process (from the call path of console_on_rootfs()). If the
+device is a console, it was already previously registered and could
+be actively printing messages.
+
+Since the startup() callback is reading/writing registers used by
+the console write() callback (AML_UART_CONTROL), its access must
+be synchronized using the port->lock. Currently it is not.
+
+The startup() callback is the only function that explicitly enables
+interrupts. Without the synchronization, it is possible that
+interrupts become accidentally permanently disabled.
+
+CPU0 CPU1
+meson_serial_console_write meson_uart_startup
+-------------------------- ------------------
+spin_lock(port->lock)
+val = readl(AML_UART_CONTROL)
+uart_console_write()
+ writel(INT_EN, AML_UART_CONTROL)
+writel(val, AML_UART_CONTROL)
+spin_unlock(port->lock)
+
+Add port->lock synchronization to meson_uart_startup() to avoid
+racing with meson_serial_console_write().
+
+Also add detailed comments to meson_uart_reset() explaining why it
+is *not* using port->lock synchronization.

+Subject: serial: sifive: Report actual baud base rather than fixed 115200
+
+From: Maciej W. Rozycki <macro@orcam.me.uk>
+
+[ Upstream commit 0a7ff843d507ce2cca2c3b7e169ee56e28133530 ]
+
+The base baud value reported is supposed to be the highest baud rate
+that can be set for a serial port. The SiFive FU740-C000 SOC's on-chip
+UART supports baud rates of up to 1/16 of the input clock rate, which is
+the bus clock `tlclk'[1], often at 130MHz in the case of the HiFive
+Unmatched board.
+
+However the sifive UART driver reports a fixed value of 115200 instead:
+
+10010000.serial: ttySIF0 at MMIO 0x10010000 (irq = 1, base_baud = 115200) is a SiFive UART v0
+10011000.serial: ttySIF1 at MMIO 0x10011000 (irq = 2, base_baud = 115200) is a SiFive UART v0
+
+even though we already support setting higher baud rates, e.g.:
+
+$ tty
+/dev/ttySIF1
+$ stty speed
+230400
+
+The baud base value is computed by the serial core by dividing the UART
+clock recorded in `struct uart_port' by 16, which is also the minimum
+value of the clock divider supported, so correct the baud base value
+reported by setting the UART clock recorded to the input clock rate
+rather than 115200:
+
+10010000.serial: ttySIF0 at MMIO 0x10010000 (irq = 1, base_baud = 8125000) is a SiFive UART v0
+10011000.serial: ttySIF1 at MMIO 0x10011000 (irq = 2, base_baud = 8125000) is a SiFive UART v0

+[ Upstream commit 2e102b53f8a778f872dc137f4c7ac548705817aa ]
+
+Normally, all channels have RX and TX queues, but this is not true if
+modparam efx_separate_tx_channels=1 is used. In that cases, some
+channels only have RX queues and others only TX queues (or more
+preciselly, they have them allocated, but not initialized).
+
+Fix efx_channel_has_tx_queues to return the correct value for this case
+too.

+
+tx_channel_offset is calculated in efx_allocate_msix_channels, but it is
+also calculated again in efx_set_channels because it was originally done
+there, and when efx_allocate_msix_channels was introduced it was
+forgotten to be removed from efx_set_channels.
+
+Moreover, the old calculation is wrong when using
+efx_separate_tx_channels because now we can have XDP channels after the
+TX channels, so n_channels - n_tx_channels doesn't point to the first TX
+channel.
+
+Remove the old calculation from efx_set_channels, and add the
+initialization of this variable if MSI or legacy interrupts are used,
+next to the initialization of the rest of the related variables, where
+it was missing.

+Subject: soundwire: intel: prevent pm_runtime resume prior to system suspend
+
+From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
+
+[ Upstream commit 6d9f2dadba698114fed97b224578c5338a36b0d9 ]
+
+commit e38f9ff63e6d ("ACPI: scan: Do not add device IDs from _CID if _HID is not valid")
+exposes a race condition on a TGL RVP device leading to a timeout.
+
+The detailed analysis shows the RT711 codec driver scheduling a jack
+detection workqueue while attaching during a spurious pm_runtime
+resume, and the work function happens to be scheduled after the
+manager device is suspended.
+
+The direct link between this ACPI patch and a spurious pm_runtime
+resume is not obvious; the most likely explanation is that a change in
+the ACPI device linked list management modifies the order in which the
+pm_runtime device status is checked and exposes a race condition that
+was probably present for a very long time, but was not identified.
+
+We already have a check in the .prepare stage, where we will resume to
+full power from specific clock-stop modes. In all other cases, we
+don't need to resume to full power by default. Adding the
+SMART_SUSPEND flag prevents the spurious resume from happening.

+
+From: Eddie James <eajames@linux.ibm.com>
+
+[ Upstream commit 61bf40ef51aa73f6216b33563271b6acf7ea8d70 ]
+
+The driver may return a timeout error even if the status register
+indicates that the transfer may proceed. Fix this by restructuring
+the polling loop.

+
+[ Upstream commit f94b47c6bde624d6c07f43054087607c52054a95 ]

+As kzalloc() may return null pointer, it should be better to

+Moreover, the return value of rtw_alloc_hwxmits() should also

+Subject: tcp: add accessors to read/set tp->snd_cwnd
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 40570375356c874b1578e05c1dcc3ff7c1322dbe ]
+
+We had various bugs over the years with code
+breaking the assumption that tp->snd_cwnd is greater
+than zero.
+
+Lately, syzbot reported the WARN_ON_ONCE(!tp->prior_cwnd) added
+in commit 8b8a321ff72c ("tcp: fix zero cwnd in tcp_cwnd_reduction")
+can trigger, and without a repro we would have to spend
+considerable time finding the bug.
+
+Instead of complaining too late, we want to catch where
+and when tp->snd_cwnd is set to an illegal value.

+Subject: tcp: tcp_rtx_synack() can be called from process context
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit 0a375c822497ed6ad6b5da0792a12a6f1af10c0b ]
+
+Laurent reported the enclosed report [1]
+
+This bug triggers with following coditions:
+
+0) Kernel built with CONFIG_DEBUG_PREEMPT=y
+
+1) A new passive FastOpen TCP socket is created.
+ This FO socket waits for an ACK coming from client to be a complete
+ ESTABLISHED one.
+2) A socket operation on this socket goes through lock_sock()
+ release_sock() dance.
+3) While the socket is owned by the user in step 2),
+ a retransmit of the SYN is received and stored in socket backlog.
+4) At release_sock() time, the socket backlog is processed while
+ in process context.
+5) A SYNACK packet is cooked in response of the SYN retransmit.
+6) -> tcp_rtx_synack() is called in process context.
+
+Before blamed commit, tcp_rtx_synack() was always called from BH handler,
+from a timer handler.
+
+Fix this by using TCP_INC_STATS() & NET_INC_STATS()
+which do not assume caller is in non preemptible context.

+Subject: tty: n_tty: Restore EOF push handling behavior
+
+From: Daniel Gibson <daniel@gibson.sh>
+
+[ Upstream commit 65a8b287023da68c4550deab5c764e6891cf1caf ]
+
+TTYs in ICANON mode have a special case that allows "pushing" a line
+without a regular EOL character (like newline), by using EOF (the EOT
+character - ASCII 0x4) as a pseudo-EOL. It is silently discarded, so
+the reader of the PTS will receive the line *without* EOF or any other
+terminating character.
+
+This special case has an edge case: What happens if the readers buffer
+is the same size as the line (without EOF)? Will they be able to tell
+if the whole line is received, i.e. if the next read() will return more
+of the same line or the next line?
+
+There are two possibilities, that both have (dis)advantages:
+
+1. The next read() returns 0. FreeBSD (13.0) and OSX (10.11) do this.
+ Advantage: The reader can interpret this as "the line is over".
+ Disadvantage: read() returning 0 means EOF, the reader could also
+ interpret it as "there's no more data" and stop reading or even
+ close the PT.
+
+2. The next read() returns the next line, the EOF is silently discarded.
+ Solaris (or at least OpenIndiana 2021.10) does this, Linux has done
+ do this since commit 40d5e0905a03 ("n_tty: Fix EOF push handling");
+ this behavior was recently broken by commit 359303076163 ("tty:
+ n_tty: do not look ahead for EOL character past the end of the buffer").
+ Advantage: read() won't return 0 (EOF), reader less likely to be
+ confused (and things like `while(read(..)>0)` don't break)
+ Disadvantage: The reader can't really know if the read() continues
+ the last line (that filled the whole read buffer) or starts a
+ new line.
+
+As both options are defensible (and are used by other Unix-likes), it's
+best to stick to the "old" behavior since "n_tty: Fix EOF push handling"
+of 2013, i.e. silently discard that EOF.
+
+This patch - that I actually got from Linus for testing and only
+modified slightly - restores that behavior by skipping an EOF
+character if it's the next character after reading is done.
+
+Based on a patch from Linus Torvalds.

+Subject: tty: serial: fsl_lpuart: fix potential bug when using both
+ of_alias_get_id and ida_simple_get
+
+From: Sherry Sun <sherry.sun@nxp.com>
+
+[ Upstream commit f398e0aa325c61fa20903833a5b534ecb8e6e418 ]
+
+Now fsl_lpuart driver use both of_alias_get_id() and ida_simple_get() in
+.probe(), which has the potential bug. For example, when remove the
+lpuart7 alias in dts, of_alias_get_id() will return error, then call
+ida_simple_get() to allocate the id 0 for lpuart7, this may confilct
+with the lpuart4 which has alias 0.
+
+ aliases {
+ ...
+ serial0 = &lpuart4;
+ serial1 = &lpuart5;
+ serial2 = &lpuart6;
+ serial3 = &lpuart7;
+ }
+
+So remove the ida_simple_get() in .probe(), return an error directly
+when calling of_alias_get_id() fails, which is consistent with other
+uart drivers behavior.

+
+From: Zhihao Cheng <chengzhihao1@huawei.com>
+
+[ Upstream commit d09e9a2bddba6c48e0fddb16c4383172ac593251 ]
+
+There at least 6 PEBs reserved on UBI device:
+1. EBA_RESERVED_PEBS[1]
+2. WL_RESERVED_PEBS[1]
+3. UBI_LAYOUT_VOLUME_EBS[2]
+4. MIN_FASTMAP_RESERVED_PEBS[2]
+
+When all ubi volumes take all their PEBs, there are 3 (EBA_RESERVED_PEBS +
+WL_RESERVED_PEBS + MIN_FASTMAP_RESERVED_PEBS - MIN_FASTMAP_TAKEN_PEBS[1])
+free PEBs. Since commit f9c34bb529975fe ("ubi: Fix producing anchor PEBs")
+and commit 4b68bf9a69d22dd ("ubi: Select fastmap anchor PEBs considering
+wear level rules") applied, there is only 1 (3 - FASTMAP_ANCHOR_PEBS[1] -
+FASTMAP_NEXT_ANCHOR_PEBS[1]) free PEB to fill pool and wl_pool, after
+filling pool, wl_pool is always empty. So, UBI could be stuck in an
+infinite loop:

+
+In commit 4b68bf9a69d22dd ("ubi: Select fastmap anchor PEBs considering
+wear level rules"), there are three key changes:
+ 1) Choose the fastmap anchor when the most free PEBs are available.
+ 2) Enable anchor move within the anchor area again as it is useful
+ for distributing wear.
+ 3) Import a candidate fm anchor and check this PEB's erase count during
+ wear leveling. If the wear leveling limit is exceeded, use the used
+ anchor area PEB with the lowest erase count to replace it.
+
+The anchor candidate can be removed, we can check fm_anchor PEB's erase
+count during wear leveling. Fix it by:
+ 1) Removing 'fm_next_anchor' and check 'fm_anchor' during wear leveling.
+ 2) Preferentially filling one free peb into fm_wl_pool in condition of
+ ubi->free_count > ubi->beb_rsvd_pebs, then try to reserve enough
+ free count for fastmap non anchor pebs after the above prerequisites
+ are met.
+Then, there are at least 1 PEB in pool and 1 PEB in wl_pool after calling
+ubi_refill_pools() with all erase works done.

+Subject: usb: dwc3: gadget: Replace list_for_each_entry_safe() if using
+ giveback
+
+From: Wesley Cheng <quic_wcheng@quicinc.com>
+
+[ Upstream commit bf594d1d0c1d7b895954018043536ffd327844f9 ]
+
+The list_for_each_entry_safe() macro saves the current item (n) and
+the item after (n+1), so that n can be safely removed without
+corrupting the list. However, when traversing the list and removing
+items using gadget giveback, the DWC3 lock is briefly released,
+allowing other routines to execute. There is a situation where, while
+items are being removed from the cancelled_list using
+dwc3_gadget_ep_cleanup_cancelled_requests(), the pullup disable
+routine is running in parallel (due to UDC unbind). As the cleanup
+routine removes n, and the pullup disable removes n+1, once the
+cleanup retakes the DWC3 lock, it references a request who was already
+removed/handled. With list debug enabled, this leads to a panic.
+Ensure all instances of the macro are replaced where gadget giveback
+is used.
+
+Example call stack:
+
+Thread#1:
+__dwc3_gadget_ep_set_halt() - CLEAR HALT
+ -> dwc3_gadget_ep_cleanup_cancelled_requests()
+ ->list_for_each_entry_safe()
+ ->dwc3_gadget_giveback(n)
+ ->dwc3_gadget_del_and_unmap_request()- n deleted[cancelled_list]
+ ->spin_unlock
+ ->Thread#2 executes
+ ...
+ ->dwc3_gadget_giveback(n+1)
+ ->Already removed!
+
+Thread#2:

+ ->waiting for dwc3 spin_lock
+ ...
+ ->Thread#1 released lock
+ ->dwc3_stop_active_transfers()
+ ->dwc3_remove_requests()
+ ->fetches n+1 item from cancelled_list (n removed by Thread#1)
+ ->dwc3_gadget_giveback()
+ ->dwc3_gadget_del_and_unmap_request()- n+1 deleted[cancelled_list]

+Subject: usb: usbip: add missing device lock on tweak configuration cmd
+
+From: Niels Dossche <dossche.niels@gmail.com>
+
+[ Upstream commit d088fabace2ca337b275d1d4b36db4fe7771e44f ]
+
+The function documentation of usb_set_configuration says that its
+callers should hold the device lock. This lock is held for all
+callsites except tweak_set_configuration_cmd. The code path can be
+executed for example when attaching a remote USB device.
+The solution is to surround the call by the device lock.
+
+This bug was found using my experimental own-developed static analysis

+Subject: usb: usbip: fix a refcount leak in stub_probe()
+
+From: Hangyu Hua <hbh25y@gmail.com>
+
+[ Upstream commit 9ec4cbf1cc55d126759051acfe328d489c5d6e60 ]
+
+usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails
+after that, usb_put_dev() needs to be called to release the reference.
+
+Fix this by moving usb_put_dev() to sdev_free error path handling.
+
+Find this by code review.

+
+The value of timer_cycle_us can be 0 due to 32bit overflow.
+For eg:- If we assign the counter value "0xfff" for computing
+maxval.
+
+This patch fixes this issue by appending ULL to 1024, so that

+Subject: watchdog: rzg2l_wdt: Fix reset control imbalance
+
+From: Biju Das <biju.das.jz@bp.renesas.com>
+
+[ Upstream commit 33d04d0fdba9fae18c7d58364643d2c606a43dba ]
+
+Both rzg2l_wdt_probe() and rzg2l_wdt_start() calls reset_control_
+deassert() which results in a reset control imbalance.
+
+This patch fixes reset control imbalance by removing reset_control_
+deassert() from rzg2l_wdt_start() and replaces reset_control_assert with
+reset_control_reset in rzg2l_wdt_stop() as watchdog module can be stopped
+only by a module reset. This change will allow us to restart WDT after
+stop() by configuring WDT timeout and enable registers.

+
+[ Upstream commit 5d24df3d690809952528e7a19a43d84bc5b99d44 ]
+
+of_parse_phandle() returns a node pointer with refcount

+Add missing of_node_put() in some error paths.
