+Subject: ALSA: hda - fix the 'Capture Switch' value change notifications
+
+From: Jaroslav Kysela <perex@perex.cz>
+
+[ Upstream commit a2befe9380dd04ee76c871568deca00eedf89134 ]
+
+The original code in the cap_put_caller() function does not
+handle correctly the positive values returned from the passed
+function for multiple iterations. It means that the change
+notifications may be lost.

+Subject: ASoC: intel: atom: Fix breakage for PCM buffer address setup
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit 65ca89c2b12cca0d473f3dd54267568ad3af55cc ]
+
+The commit 2e6b836312a4 ("ASoC: intel: atom: Fix reference to PCM
+buffer address") changed the reference of PCM buffer address to
+substream->runtime->dma_addr as the buffer address may change
+dynamically. However, I forgot that the dma_addr field is still not
+set up for the CONTINUOUS buffer type (that this driver uses) yet in
+5.14 and earlier kernels, and it resulted in garbage I/O. The problem
+will be fixed in 5.15, but we need to address it quickly for now.
+
+The fix is to deduce the address again from the DMA pointer with
+virt_to_phys(), but from the right one, substream->runtime->dma_area.

+Subject: btrfs: prevent rename2 from exchanging a subvol with a directory from
+ different parents
+
+From: NeilBrown <neilb@suse.de>
+
+[ Upstream commit 3f79f6f6247c83f448c8026c3ee16d4636ef8d4f ]
+
+Cross-rename lacks a check when that would prevent exchanging a
+directory and subvolume from different parent subvolume. This causes
+data inconsistencies and is caught before commit by tree-checker,
+turning the filesystem to read-only.
+
+Calling the renameat2 with RENAME_EXCHANGE flags like
+
+ renameat2(AT_FDCWD, namesrc, AT_FDCWD, namedest, (1 << 1))
+
+on two paths:
+
+ namesrc = dir1/subvol1/dir2
+ namedest = subvol2/subvol3
+
+will cause key order problem with following write time tree-checker

+
+The corrupted data will not be written, and filesystem can be unmounted
+and mounted again (all changes since the last commit will be lost).
+
+Add the missing check for new_ino so that all non-subvolumes must reside
+under the same parent subvolume. There's an exception allowing to
+exchange two subvolumes from any parents as the directory representing a
+subvolume is only a logical link and does not have any other structures
+related to the parent subvolume, unlike files, directories etc, that
+are always in the inode namespace of the parent subvolume.

+Subject: ipack: tpci200: fix many double free issues in tpci200_pci_probe
+
+From: Dongliang Mu <mudongliangabcd@gmail.com>
+
+[ Upstream commit 57a1681095f912239c7fb4d66683ab0425973838 ]
+
+The function tpci200_register called by tpci200_install and
+tpci200_unregister called by tpci200_uninstall are in pair. However,
+tpci200_unregister has some cleanup operations not in the
+tpci200_register. So the error handling code of tpci200_pci_probe has
+many different double free issues.
+
+Fix this problem by moving those cleanup operations out of
+tpci200_unregister, into tpci200_pci_remove and reverting
+the previous commit 9272e5d0028d ("ipack/carriers/tpci200:
+Fix a double free in tpci200_pci_probe").

+Subject: ipack: tpci200: fix memory leak in the tpci200_register
+
+From: Dongliang Mu <mudongliangabcd@gmail.com>
+
+[ Upstream commit 50f05bd114a46a74726e432bf81079d3f13a55b7 ]
+
+The error handling code in tpci200_register does not free interface_regs
+allocated by ioremap and the current version of error handling code is
+problematic.
+
+Fix this by refactoring the error handling code and free interface_regs
+when necessary.

+Subject: locks: print a warning when mount fails due to lack of "mand" support
+
+From: Jeff Layton <jlayton@kernel.org>
+
+[ Upstream commit df2474a22c42ce419b67067c52d71da06c385501 ]
+
+Since 9e8925b67a ("locks: Allow disabling mandatory locking at compile
+time"), attempts to mount filesystems with "-o mand" will fail.
+Unfortunately, there is no other indiciation of the reason for the
+failure.
+
+Change how the function is defined for better readability. When
+CONFIG_MANDATORY_FILE_LOCKING is disabled, printk a warning when
+someone attempts to mount with -o mand.
+
+Also, add a blurb to the mandatory-locking.txt file to explain about
+the "mand" option, and the behavior one should expect when it is
+disabled.

++7. The "mand" mount option
++--------------------------
++Mandatory locking is disabled on all filesystems by default, and must be
++administratively enabled by mounting with "-o mand". That mount option
++is only allowed if the mounting task has the CAP_SYS_ADMIN capability.
++
++Since kernel v4.5, it is possible to disable mandatory locking
++altogether by setting CONFIG_MANDATORY_FILE_LOCKING to "n". A kernel
++with this disabled will reject attempts to mount filesystems with the
++"mand" mount option with the error status EPERM.

+Subject: mmc: dw_mmc: Fix hang on data CRC error
+
+From: Vincent Whitchurch <vincent.whitchurch@axis.com>
+
+[ Upstream commit 25f8203b4be1937c4939bb98623e67dcfd7da4d1 ]
+
+When a Data CRC interrupt is received, the driver disables the DMA, then
+sends the stop/abort command and then waits for Data Transfer Over.
+
+However, sometimes, when a data CRC error is received in the middle of a
+multi-block write transfer, the Data Transfer Over interrupt is never
+received, and the driver hangs and never completes the request.
+
+The driver sets the BMOD.SWR bit (SDMMC_IDMAC_SWRESET) when stopping the
+DMA, but according to the manual CMD.STOP_ABORT_CMD should be programmed
+"before assertion of SWR". Do these operations in the recommended
+order. With this change the Data Transfer Over is always received
+correctly in my tests.

+
+The Renoir XHCI controller apparently doesn't resume reliably with the
+standard D3hot-to-D0 delay. Increase it to 20ms.
+
+[Alex: I talked to the AMD USB hardware team and the AMD Windows team and
+they are not aware of any HW errata or specific issues. The HW works fine
+in Windows. I was told Windows uses a rather generous default delay of
+100ms for PCI state transitions.]

+
+In some usecases transaction ids are dynamically allocated inside

+acknowledge responses. So check for this before refcounting pm_runtime.
+
+Without this we would end up imbalancing runtime pm count by

+
+The problem was the "trace(read_max,count)" where the "count" should be
+"$count" as "onmax()" only handles variables (although it really should be
+able to figure out that "count" is a field of sys_enter_read). But there's
+a path that does not find the variable and ends up passing a NULL for the
+event, which ends up getting passed to "strcmp()".
+
+Add a check for NULL to return and error on the command with:
+
+ # cat error_log
+ hist:syscalls:sys_enter_read: error: Couldn't create or find variable
+ Command: hist:keys=common_pid:count=count:onmax($count).trace(read_max,count)
