The amdisp i2c device requires ISP to be in power-on state for probe

to control ISP power using runtime PM. The pm_runtime_get_sync() called

invokes the amdisp i2c runtime resume before the probe completes resulting

- Call dev_pm_genpd_suspend() to Power OFF ISP after probe
- Set the device to suspended state with pm_runtime_set_suspended()
- Enable runtime PM only after the device is fully initialized

The driver was disabling the USB2 PHY clock immediately after register
initialization in probe() and after each reset operation. This left the

The behavior appeared to work only when another driver
(e.g., USB controller) had already enabled the clock, making operation
unreliable and hardware-dependent. In configurations where this driver
is the sole clock user, USB functionality would fail.
Fix this by:
- Enabling the clock once in probe() via pm_runtime_resume_and_get()
- Removing all pm_runtime_put() calls from assert/deassert/status
- Registering a devm cleanup action to release the clock at removal
- Removed rzv2h_usbphy_assert_helper() and its call in

Convert 'aux_priv' and 'edev' members of struct bnxt into

Make callers of bnxt_ulp_start() call it only when there
are no errors.
Also, as an improvement in code, bnxt_register_dev() can skip
unnecessary dereferencing of edev from bp, instead use the
edev pointer from the function parameter.

net: ti: icssg-prueth: fix missing data copy and wrong recycle in ZC RX dispatch
emac_dispatch_skb_zc() allocates a new skb via napi_alloc_skb() but
never copies the packet data from the XDP buffer into it. The skb is
passed up the stack containing uninitialized heap memory instead of
the actual received packet, leaking kernel heap contents to userspace.
Copy the received packet data from the XDP buffer into the skb using
skb_copy_to_linear_data().
Additionally, remove the skb_mark_for_recycle() call since the skb is
backed by the NAPI page frag allocator, not page_pool. Marking a
non-page_pool skb for recycle causes the free path to return pages to
a page_pool that does not own them, corrupting page_pool state.
The non-ZC path (emac_rx_packet) does not have these issues because it
uses napi_build_skb() to wrap the existing page_pool page directly,
requiring no copy, and correctly marks for recycle since the page comes
from page_pool_dev_alloc_pages().

ovl: make fsync after metadata copy-up opt-in mount option
Commit 7d6899fb69d25 ("ovl: fsync after metadata copy-up") was done to
fix durability of overlayfs copy up on an upper filesystem which does
not enforce ordering on storing of metadata changes (e.g. ubifs).
In an earlier revision of the regressing commit by Lei Lv, the metadata
fsync behavior was opt-in via a new "fsync=strict" mount option.
We were hoping that the opt-in mount option could be avoided, so the
change was only made to depend on metacopy=off, in the hope of not
hurting performance of metadata heavy workloads, which are more likely
to be using metacopy=on.
This hope was proven wrong by a performance regression report from Google
COS workload after upgrade to kernel 6.12.
This is an adaptation of Lei's original "fsync=strict" mount option
to the existing upstream code.
The new mount option is mutually exclusive with the "volatile" mount
option, so the latter is now an alias to the "fsync=volatile" mount
option.

rust: list: hide macros from top-level kernel doc
Due to Rust macro scoping rules, all macros defined in a crate using
`#[macro_export]` end up in the top-level. For the list macros, we
re-export them inside the list module, and expect users to use
`kernel::list::macro_name!()`.
Use `#[doc(hidden)]` on the macro definition, and use `#[doc(inline)]` on
the re-export to make the macro appear to be defined at module-level inside
documentation.
The other exported types are already automatically `#[doc(inline)]` because
they are defined in a non-public module, so there is no need to split the
macro re-exports out.
It should have been there since the beginning, and while it is not a big
deal since the file has not changed at all since it was added in commit 80db40bac8f4 ("rust: add `.rustfmt.toml`") back in 2022, this will be
especially useful to catch unintended unstable features if upstream
`rustfmt` started to allow them in stable toolchains [1][2].

drm/i915/uncore: Do GT FIFO checks in early sanitize and forcewake get
We're mixing up the GT FIFO debug checks (overflows and such)
with RMbus unclaimed register checks. The two are quite different
things as RMbus is only relevant for display registers, and the
GT FIFO only relevant for GT registers.
Split the GT FIFO debugs out from the unclaimed register logic
and just do the checks during forcewake_get() and early init.
That is still sufficient to detect if any errors have happened.
Any errors would anyway be caused by overflowing the FIFO
rather than accessing specific registers, so trying to figure
out exactly when the error happened isn't particularly useful.
To fix such issues we'd rather have to do something to slow down
the rate at which registers are accessed (eg. increase
GT_FIFO_NUM_RESERVED_ENTRIES or something).
The live_forcewake_domains selftest doesn't really test anything
particularly sensible. It only runs on platforms that have RMbus
unclaimer error detection, but that only catches display registers
which the test doesn't even access.
I suppose if we really wanted to we might try to make the test
exercise the GT FIFO instead by writing GT registers as fast
as possible, and then checking GTFIFODBG to see if the FIFO has
overflowed. But dunno if there's much point in that. I think a
GT FIFO overflow might even be fatal to the machine.
So in its current for the test doesn't really make sense,
and it's in the way of moving all the RMbus noclaim stuff
to the display driver side. So let's just get rid of it.

leads to:
[drm] Missing drm_bridge_add() before attach
Add the missing call, using devm_drm_bridge_add() variant to get the
drm_bridge_remove() handled automatically.
The commit marked with the Fixes tag (from v6.6) is the commit that
added the encoder bridge without drm_bridge_add(). However, this fix is
not directly applicable there as devm_drm_bridge_alloc() was not used to
alloc the bridge, so using devm version for drm_bridge_add() wouldn't be
safe. Instead, drm_bridge_add() and drm_bridge_remove() would be needed
there, but that would require new plumbing code as we don't have a
separate cleanup function in the tidss_encoder.c, not in the tidss_kms.c
from which the encoder is created.
Also, there has been no reported bugs caused by the missing
drm_bridge_add(). The drm_bridge_add() initializes the bridge's
hpd_mutex, but HPD is not used for the encoder bridge. drm_bridge_add()
also adds the bridge to the global bridge_list, which is only used in
of_drm_find_bridge(), and again that is not used for the encoder bridge.
Thus, while the original commit is not right, there should be no bugs
caused by it, and for the time being I'm not sending a patch for the
stable kernels for the original commit.
This fix applies on top of commit 66cdf05f8548 ("drm/tidss: encoder:

crypto: hisilicon/sec2 - prevent req used-after-free for sec
During packet transmission, if the system is under heavy load,
the hardware might complete processing the packet and free the
request memory (req) before the transmission function finishes.
If the software subsequently accesses this req, a use-after-free
error will occur. The qp_ctx memory exists throughout the packet
sending process, so replace the req with the qp_ctx.

crypto: inside-secure/eip93 - make it selectable for ECONET
Econet SoCs feature an integrated EIP93 in revision 3.0p1. It is identical
to the one used by the Airoha AN7581 and the MediaTek MT7621. Ahmed reports
that the EN7528 passes testmgr's self-tests. This driver should also work
on other little endian Econet SoCs.

crypto: testmgr - Add test vectors for authenc(hmac(md5),rfc3686(ctr(aes)))
Test vectors were generated starting from existing RFC3686(CTR(AES)) test
vectors and adding HMAC(MD5) computed with software implementation.
Then, the results were double-checked on Mediatek MT7986 (safexcel).
Platform pass self-tests.
