There are no remaining static platform_device users of pxa2xx ac97,
so the rest of that code path can go away as well.
Since nothing in the driver uses the gpio number now, constrain the use
of the legacy gpio interface to the architecture specific code.

Redirect wm_adsp_release_firmware_files() to a replacement function that
handles the dummy firmware created by the tests. Use the same cleanup
function to cleanup in the test exit() function. Also call it on each
loop in wm_adsp_fw_find_test_find_firmware_byindex() to free the created
strings before reusing priv->found_fw on the next loop.
wm_adsp_release_firmware_files() will pass the struct firmware* pointers
to release_firmware(). But the pointers created by the tests are dummies
and must not be passed to release_firmware().
The test never invokes wm_adsp_release_firmware_files() so it wasn't
redirected. But the error handling in wm_adsp_request_firmware_files()
calls wm_adsp_release_firmware_files(). The redirected function makes
this safe.
Using the same cleanup function to perform cleanup from the test exit()
handler and wm_adsp_fw_find_test_find_firmware_byindex() avoids the risk
of duplicate cleanup code that all needs updating if there is any change
to the cleanup requirements.

Add a simple ASoC machine driver that wires the MT2701/MT7623N
AFE HDMI playback path to the on-chip HDMI transmitter exposed
as a generic hdmi-audio-codec "i2s-hifi" DAI.
The driver binds to "mediatek,mt2701-hdmi-audio". MT7623N device

Extend the MT2701/MT7623N AFE driver with the HDMI playback path:
- a new HDMI DMA memif (MT2701_MEMIF_HDMI) mapped to the
AFE_HDMI_OUT_{CON0,BASE,CUR,END} registers;
- a PCM_HDMI front-end DAI (S16_LE only, 44.1k/48k) which feeds
the memif via DPCM;
- an HDMI BE DAI wrapping the AFE_8CH_I2S_OUT_CON engine that
serialises L/R samples towards the on-chip HDMI transmitter.
Sample-rate programming uses the empirically determined
HDMI_BCK_DIV = 45 * 48000 / rate - 1 formula in AUDIO_TOP_CON3,
which covers 44.1 kHz and 48 kHz within the 6-bit divider range.
The AFE_HDMI_CONN0 interconnect is programmed to route memif
output pairs to the serializer inputs with L/R in the right order
for hdmi-audio-codec.
The existing I2S engine helpers (mt2701_mclk_configuration,
mt2701_i2s_path_enable, mt2701_afe_i2s_path_disable) are reused
for the HDMI BE so that MCLK at 128*fs and the ASYS I2S3 FS field
are programmed and cleanly released across open/close cycles.
Only S16_LE and 44.1k/48k are exposed to userspace. Other rates
fall outside the 6-bit BCK divider range, and wider sample
formats require DMA BIT_WIDTH programming that the current memif
setup does not handle. These limits match what the MT8173 AFE
driver exposes for its HDMI path.
The HDMI-related AFE registers (AUDIO_TOP_CON3, AFE_HDMI_OUT_CON0,
AFE_HDMI_CONN0, AFE_8CH_I2S_OUT_CON) are added to the suspend
backup list so that the existing mtk_afe_suspend/resume framework
saves and restores them across system sleep cycles.

There are some short comings of the current SDCA class driver with
respect to duplicated functions and jacks. Fix some issues in the
reporting of jacks when there are multiple jacks represented in the SDCA
topology. When a single device contains multiple instances of the same
type of SDCA function the current class driver will create duplicate
controls, update the code to fix this. Finally whilst working through
this also tidy up the handling of the sdca_function_desc pointers as it
turns out some duplication has crept into the code on that front.
It is possible that SDCAs devices might have multiple functions of
the same type, as the entity names within a function are defined by
the specification it is very likely such a device will have duplicate
entities. This causes problems where DAIs and ALSA controls end up
with clashing names.
This can be handled by adding the function address into the names to
ensure uniqueness, although, ideally this would have been included from
the start. User-space already has UCM using the current control names,
so as a compromise the first function of a given type will use the
raw entity names, then duplicates will get an added function address.

The class driver internally has an array of sdca_function_data pointers
that it uses to store the parsed DisCo data. However, there is already
an sdca_function_data attached to the auxdev device. It makes more sense
to use the one already provided in the auxdev device, as it could also
be used by custom drivers for parts that require those.
Using the auxdev copy also prevents the need for the class function
drivers to search through the array for the correct data, which
currently is based off matching the function type. This has problems
when two functions have the same type as the current code will find the
same data for both drivers, using the auxdev copy of the data avoids
this problem.

Currently, all SDCA jacks simply report against a mask of 0xFFFF. This
works fine for system with a single SDCA jack control as the status
reflects that single control at all times. However, if two SDCA
jack controls exist in the system, such as a separate representation for
input and output, then the second control can cancel reports from the
other since it will only report its relevant bits and zero in all other
slots. This is exactly what the mask is for.
Build up a mask using all the possible states for an SCDA jack control
at registration time and use that mask when reporting a particular jack.
It is worth noting this still doesn't handle cases such as two headphone
jacks as that would require separate ALSA jacks to report to.

Pull selinux fixes from Paul Moore:
- Ensure SELinux is always properly accessing its own sock LSM state
- Only reserve an xattr slot for SELinux if it will be used
- Fix a SELinux auditing regression in the directory avdcache
* tag 'selinux-pr-20260501' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux:
selinux: fix avdcache auditing
selinux: don't reserve xattr slot when we won't fill it
selinux: use sk blob accessor in socket permission helpers
Currently need_futex_hash_allocate_default() depends on strict pthread
semantics, abusing CLONE_THREAD. This breaks the non-concurrency
assumptions when doing the mm->futex_ref pcpu allocations, leading to
bugs[0] when sharing the mm in other ways; ie:
BUG: KASAN: slab-use-after-free in futex_hash_put
... where the +1 bias can end up on a percpu counter that mm->futex_ref
no longer points at.
Loosen the check to cover any CLONE_VM clone, except vfork(). Excluding
vfork keeps the existing paths untouched (no overhead), and we can't
race in the first place: either the parent is suspended and the child
runs alone, or mm->futex_ref is already allocated from an earlier
CLONE_VM.
