There's not much use in passing a number to the macro and let it
convert that into the enum and a string. It just hides the symbols.
Remove the number to enum conversion magic in intel_display_wa().
This has the side-effect of changing the print in the drm_WARN() that
is issued when the number is not implemented, but that is moot anyway
and can be changed later to something cleaner if needed.

When a write subrequest is marked NETFS_SREQ_NEED_RETRY, the retry path
in netfs_unbuffered_write() unconditionally calls stream->prepare_write()
without checking if it is NULL.
Filesystems such as 9P do not set the prepare_write operation, so
stream->prepare_write remains NULL. When get_user_pages() fails with
-EFAULT and the subrequest is flagged for retry, this results in a NULL
pointer dereference at fs/netfs/direct_write.c:189.
Fix this by mirroring the pattern already used in write_retry.c: if
stream->prepare_write is NULL, skip renegotiation and directly reissue
the subrequest via netfs_reissue_write(), which handles iterator reset,
IN_PROGRESS flag, stats update and reissue internally.

With everything else now in place, we can convert the remaining parts of
the reset subsystem to becoming fwnode-agnostic - meaning it will work
with all kinds of firmware nodes, not only devicetree.
To that end: extend struct reset_controller_dev with fields taking
information relevant for using firmware nodes (which mirrors what we
already do for OF-nodes) and limit using of_ APIs only to where it's
absolutely necessary (mostly around the of_xlate callback).
For backward compatibility of existing drivers we still support OF-nodes
but firmware nodes become the preferred method.

Except for the reset-gpio, all reset drivers use device tree - and as
such - benefit from the device links set up by driver core. This means,
that no reset supplier will be unbound before all its consumers have
been. For this reason, nobody bothered making the reset core resiliant
to the object life-time issues that are plagueing the kernel. In this
case: reset control handles referencing the reset provider device with
no serialization or NULL-pointer checking.
We now want to make the reset core fwnode-agnostic but before we do, we
must make sure it can survive unbinding of suppliers with consumers
still holding reset control handles.
To that end: use SRCU to protect the rcdev pointer inside struct
reset_control. We protect all sections using the pointer with SRCU
read-only critical sections and synchronize SRCU after every
modification of the pointer.
This is in line with what the GPIO subsystem does and what the proposed
revocable API tries to generalize. When and if the latter makes its way
into the kernel, reset core could potentially also be generalized to use
it.

The of_args field of struct reset_controller_dev was introduced to allow

The thing is: it doesn't even have to do it. The core sets the platform

lookup. This means the field is unneeded and all can happen entirely in
reset core.

The device that requests the reset control managed by the reset-gpio

When a process crashes and the kernel writes a core dump to a 9P
filesystem, __kernel_write() creates an ITER_KVEC iterator. This
iterator reaches netfs_limit_iter() via netfs_unbuffered_write(), which
only handles ITER_FOLIOQ, ITER_BVEC and ITER_XARRAY iterator types,
hitting the BUG() for any other type.
Fix this by adding netfs_limit_kvec() following the same pattern as
netfs_limit_bvec(), since both kvec and bvec are simple segment arrays
with pointer and length fields. Dispatch it from netfs_limit_iter() when
the iterator type is ITER_KVEC.

Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.
Drop the redundant device reference to reduce cargo culting, make it
easier to spot drivers where an extra reference is needed, and reduce
the risk of memory leaks when drivers fail to release it.

Currently Tyr defines a convenience type alias for its DRM device type,
`TyrDrmDevice` but it does not use the alias outside of `tyr/driver.rs`.
Replace `drm::Device<TyrDrmDriver>` with the alias `TyrDrmDevice` across
the driver.
This change will ease future upstream Tyr development by reducing the
diffs when multiple series are touching these files.
No functional changes are intended.

The NPU 60XX uses the default boot params location specified
in the firmware image header, consistent with earlier generations.
Remove the unnecessary MMIO register write, freeing the AON register
for future use.

The Lenovo ThinkPad X390 (ALC257 codec, subsystem ID 0x17aa2288)
does not report headset button press events. Headphone insertion is
detected (SW_HEADPHONE_INSERT), but pressing the inline microphone
button on a headset produces no input events.
Add a SND_PCI_QUIRK entry that maps this subsystem ID to
ALC285_FIXUP_THINKPAD_NO_BASS_SPK_HEADSET_JACK, which enables
headset jack button detection through alc_fixup_headset_jack()
and ThinkPad ACPI integration. This is the same fixup used by
similar ThinkPad models (P1 Gen 3, X1 Extreme Gen 3).

HP Laptop 14s-dr5xxx with ALC236 codec does not handle the toggling of
the mute LED.
This patch adds a quirk entry for subsystem ID 0x8a1f using
ALC236_FIXUP_HP_MUTE_LED_COEFBIT2 fixup, enabling correct mute LED
behavior.

In the drain loop, the local variable 'runtime' is reassigned to a
linked stream's runtime (runtime = s->runtime at line 2157). After
releasing the stream lock at line 2169, the code accesses
runtime->no_period_wakeup, runtime->rate, and runtime->buffer_size
(lines 2170-2178) — all referencing the linked stream's runtime without
any lock or refcount protecting its lifetime.
A concurrent close() on the linked stream's fd triggers
snd_pcm_release_substream() → snd_pcm_drop() → pcm_release_private()
→ snd_pcm_unlink() → snd_pcm_detach_substream() → kfree(runtime).
No synchronization prevents kfree(runtime) from completing while the
drain path dereferences the stale pointer.
Fix by caching the needed runtime fields (no_period_wakeup, rate,
buffer_size) into local variables while still holding the stream lock,
and using the cached values after the lock is released.

NeilBrown <neilb@ownmail.net> says:
I am working towards changing the locking rules for name-operations: locking
the name rather than the whole directory.
The current part of this process is centralising all the locking so that
it can be changed in one place.
Recently "start_creating", "start_removing", "start_renaming" and related
interaces were added which combine the locking and the lookup. At that time
many callers were changed to use the new interfaces. However there are still
an assortment of places out side of fs/namei.c where the directory is locked
explictly, whether with inode_lock() or lock_rename() or similar. These were
missed in the first pass for an assortment of uninteresting reasons.
This series addresses the remaining places where explicit locking is
used, and changes them to use the new interfaces, or otherwise removes
the explicit locking.
The biggest changes are in overlayfs. The other changes are quite
simple, though maybe the cachefiles changes is the least simple of those.
I'm running the --overlay tests in xfstests and nothing has popped yet.
I'll continue with this and run some NFS tests too.
