When a keep-alive (KAE) silent stream is active on an Intel HDMI/DP
codec, opening a real PCM stream reprograms the converter format and the
audio infoframe in snd_hda_hdmi_generic_pcm_prepare(). Part of that
reprogramming - the converter channel count and the channel mapping in
snd_hda_hdmi_setup_audio_infoframe() - is not safe to do while a
keep-alive stream is active. This is most visible when switching to a
multichannel PCM configuration, where the active channel count actually
changes. In that case the newly opened PCM stream plays no sound.
Add an optional hdmi_ops .prepare hook, called at the start of the
PCM prepare sequence (before the format and infoframe are touched), and
implement it for HSW+ to release keep-alive. Keep-alive is then
re-enabled as before once the new stream has been set up, in the
setup_stream op.

cs35l41_get_acpi_mute_state() evaluates a _DSM method to get the ACPI
mute state and reads the first byte from the returned object.
However, the returned ACPI object is owned by the caller and is never
freed after use, so each successful query leaks the _DSM result object.
The code also assumes that the returned object is a buffer with at least
one byte. A malformed firmware response can return a different object
type or an empty buffer, and the direct ret->buffer.pointer dereference
can then access an invalid pointer.
Use the typed _DSM helper, validate that the returned buffer contains at
least one byte, and free the ACPI object after reading it.

queue_delete() closes the queue timer, then frees it. snd_seq_timer_close()
clears q->timer->timeri. snd_use_lock_sync() then drains borrowers, and
snd_seq_timer_delete() frees q->timer.
A borrower can re-open the timer inside that window. A SET_QUEUE_CLIENT
that took a queueptr() use_lock reference before the queue was unlinked
runs snd_seq_timer_open() after the close. Open refuses re-open only while
timeri is set, and the close just cleared it, so it re-opens timeri.
snd_seq_timer_delete() does not close that instance. Its snd_seq_timer_stop()
is a no-op, because running was cleared first. So it frees q->timer with the
instance still live. The queue is freed next.
The instance stays on the global timer with callback_data pointing at the
freed queue. A non-owner START on the unlocked queue arms it. The next tick
derefs the freed queue in snd_seq_timer_interrupt().
Reachable by an unprivileged user with access to /dev/snd/seq. No CAP and
no queue ownership required.
Close any lingering instance in the destructor. There, ->timeri can no
longer change: the queue is unlinked and all use_lock borrowers have
drained, so no snd_seq_queue_use() can re-open it. Close it before clearing
q->timer. snd_timer_close() waits for any in-flight snd_seq_timer_interrupt()
to finish, and that callback still reads q->timer (via snd_seq_check_queue()),
so q->timer must stay valid until it drains.

Some units of the Lenovo Legion Pro 7 16ARX8H (82WS) report codec

Salvador reported that the recent fix for applying the DSD quirk to
Musical Fidelity devices broke for his M6s DAC model (2772:0502).
Although this is basically a firmware bug, the model in question is
fairly old, and no further firmware update can be expected, so it'd be
better to address in the driver side.
As an ad hoc workaround, skip the DSD quirk for this device by adding
an empty quirk entry of 2772:0502; this essentially skips the later
DSD quirk entry by the match with the vendor 2772.

Make the Kconfig item for cirrus_scodec visible if CONFIG_KUNIT is
enabled. This is so that its KUnit test can be enabled by KUnit
scripts without requiring a large amount of irrelevant additional
components.
The general rule for KUNIT_ALL_TESTS is that it should only enable
tests for components that are already selected. However, the UML
environment does not support ACPI, which means the HDA codec drivers
that use cirrus_scodec cannot be selected. But cirrus_scodec does not
need ACPI.
By making the Kconfig option visible if CONFIG_KUNIT, the KUnit test
can be enabled with only the minimal set of functionality that is
required for cirrus_scodec.
This is still compliant with the KUNIT_ALL_TESTS rule "only tests
for enabled modules" because by default cirrus_scodec will only be
enabled if the drivers that use it are enabled. It must be
intentionally enabled to force it to be included for testing.

In tas2562_parse_dt(), the fallback lookup for the deprecated
"shut-down" GPIO property is broken due to a missing pair of braces.
The code intends to reset sdz_gpio to NULL only when the lookup
returns an error that is not -EPROBE_DEFER (so the driver gracefully
continues without a GPIO). However, without braces the statement:
tas2562->sdz_gpio = NULL;
falls outside the IS_ERR() check and is executed unconditionally
for every path through the if block, including a successful GPIO
lookup.
This means any device using the deprecated 'shut-down' DT property
will always have sdz_gpio == NULL after probe, making the GPIO
completely non-functional.
Fix this by adding the missing braces to scope the NULL assignment
inside the IS_ERR() branch, matching the pattern already used for
the primary 'shutdown' GPIO lookup above.

reports a constant value on GET_CUR for its PCM Playback Volume

trips the sticky-value detection in check_sticky_volume_control(),
which disables the mixer control entirely:

As a result, the device boots with playback volume effectively muted

Apply QUIRK_FLAG_MIXER_GET_CUR_BROKEN so the sticky check marks the
control as get_cur_broken and relies on the cached value instead of
disabling the mixer control outright.
Tested by backporting this quirk flag and the supporting
get_cur_broken logic onto a Linux 7.1.2-zen kernel build that does
not yet carry it, and confirming that after applying the flag the
kernel log changes from
usb 1-4: 5:0: sticky mixer values (0/100/1 => 80), disabling
to

is likely why this has not been noticed widely.

correct for a ThinkPad, but here the shared DAC is exposed as a
"Line Out" control that defaults to zero, so the headphones stay
silent when plugged in.

amplifier and the headset jack without the ThinkPad DAC sharing, and
routes the speaker to DAC 0x02 so the headphone and speaker get
independent DACs.

On ThinkPad X1 Carbon Gen 13 (Lunar Lake, RT712-SDCA version VA) the
3.5mm headphone jack is silent after rebooting from Windows.
rt712_sdca_va_io_init() gates rt712_sdca_calibration() on the persisted
vendor SW_CONFIG1 flag, and io_init writes SW_CONFIG1=1 at the end
regardless of whether the calibration succeeded. Across a warm reboot
the codec keeps power, so SW_CONFIG1 stays unchanged, the calibration
may be skipped, and the retained state can be invalid, leaving the
headphone amp disabled.
This patch mimics the reset sequence in rt711-sdca.c, it adds an
rt712_sdca_reset() helper, and calls it from io_init so the codec is
reset before initialization. RT712_PARA_VERB_CTL,
RT712_HIDDEN_REG_SW_RESET and RT712_HDA_LEGACY_RESET_CTL are already
defined but were unused. The reset clears SW_CONFIG1 and the analog
state so rt712_sdca_calibration() runs from a clean state and
completes.
Problem reproducible: boot Windows (headphone is good) -> reboot
to Linux (silent).
The reproducibility may depend on Windows' behaviour.

Pull spi fixes from Mark Brown:
"A small set of fixes that came in since -rc1, we have one core fix for
shutting down target mode properly if the system suspends while it's
running plus a small set of fairly unremarkable device specific fixes.
There's also a couple of pure DT binding changes for Renesas SoCs, the
power domains one allows some SoCs to be correctly described with
existing code"

spi: core: Abort active target transfer on controller suspend
spi: sh-msiof: abort transfers when reset times out
usb_ep1_command_reply_dispatch() uses buf[0] as a command byte and then
reads command-specific fixed items from the same URB buffer. Several
paths use buf + 1, buf[1], buf[2], or buf + 3 without first proving that
urb->actual_length contains those bytes.
Add per-command length checks, use a payload length derived from the
bytes after the command byte for the control-state copy, and reject short
analog input payloads before the input helper reads fixed offsets from
the EP1 reply.
