This reverts commit ff878b408a.
Unfortunately the recent fix seems bringing another regressions with
PulseAudio / pipewire, at least for Steinberg and MOTU devices.
As a temporary solution, do a straight revert. The issue for Android
will be revisited again later by another different fix (if any).

During the code change to add the support for devres-managed card
instance, we put an explicit kfree(card) call at the error path in
snd_card_new(). This is needed for the early error path before the
card is initialized with the device, but is rather superfluous and
causes a double-free at the error path after the card instance is
initialized, as the destructor of the card object already contains a
kfree() call.
This patch fixes the double-free situation by removing the superfluous
kfree(). Meanwhile we need to call kfree() explicitly for the early
error path, so it's added there instead.

it is no longer allocated for the silent stream. Clear the appropriate

be applied in hdmi_pcm_close() (and the error path - open fcn) again.
If the flag is not cleared, the reuse conditions for the silent

We fixed the potential deadlock at dynamic unbinding the HD-audio
codec at the commit 7206998f57 ("ALSA: hda: Fix potential deadlock
at codec unbinding"), but ironically, this caused another potential
deadlock. The current code uses refcount_dec() and waits for the
pending task with wait_event for dropping the refcount to 0. This
works fine when PCMs are assigned and actually waiting for the
refcount drop.
Meanwhile, when there was no PCM assigned, the refcount_dec() call
itself was supposed to drop to zero -- alas, it doesn't in reality;
refcount_dec() complains, spews kernel warning and it saturates
instead of dropping to 0, due to the nature of refcount_dec()
implementation. This eventually blocks the wait_event() wakeup and
the code get stuck there.
For avoiding the problem, we call refcount_dec_and_test() and skips
the sync-wait if it already reaches to zero.
The patch does a slight code reshuffling to make sure to invoke other
disconnect calls before the sync-wait, too.

ASoC: Fixes for v6.0
Quite a few fixes here, all driver specific and fairly small.
The recent commit c11117b634 ("ALSA: usb-audio: Refcount multiple
accesses on the single clock") tries to manage the clock rate shared
by several endpoints. This was intended for avoiding the unmatched
rate by a different endpoint, but unfortunately, it introduced a
regression for PulseAudio and pipewire, too; those applications try to
probe the multiple possible rates (44.1k and 48kHz) and setting up the
normal rate fails but only the last rate is applied.
The cause is that the last sample rate is still left to the clock
reference even after closing the endpoint, and this value is still
used at the next open. It happens only when applications set up via
PCM prepare but don't start/stop the stream; the rate is reset when
the stream is stopped, but it's not cleared at close.
This patch addresses the issue above, simply by clearing the rate set
in the clock reference at the last close of each endpoint.

The voice allocator sometimes begins allocating from near the end of the
array and then wraps around, however snd_emu10k1_pcm_channel_alloc()
accesses the newly allocated voices as if it never wrapped around.
This results in out of bounds access if the first voice has a high enough
index so that first_voice + requested_voice_count > NUM_G (64).
The more voices are requested, the more likely it is for this to occur.
This was initially discovered using PipeWire, however it can be reproduced
by calling aplay multiple times with 16 channels:

The last fix for trying to recover the regression on AMD platforms,
unfortunately, leaded to yet another regression: it turned out that
IOMMUs don't like the usage of raw page allocations.
This is yet another attempt for addressing the log saga; at this time,
we re-use the existing buffer allocation mechanism with SG-pages
although we require only single pages. The SG buffer allocation
itself was confirmed to work for stream buffers, so it's relatively
easy to adapt for other places.
The only problem is: although the HD-audio code is accessing the
address directly via dmab->address field, SG-pages don't set up it.
For the ease of adaption, we now set up the dmab->addr field from the
address of the first page as default, so that it can run with the
HD-audio driver code as-is without the excessive call of
snd_sgbuf_get_addr() multiple times; that's the only change in the
memalloc helper side. The rest is nothing but a flip of the dma_type
field in the HD-audio side.

There is a small race window at snd_pcm_oss_sync() that is called from
OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls

for the rest. When the stream is set up again by another thread
between them, it leads to inconsistency, and may result in unexpected
results such as NULL dereference of OSS buffer as a fuzzer spotted
recently.
The fix is simply to cover snd_pcm_oss_make_ready() call into the same

One of the former changes for the endpoint management was the more
consistent setup of endpoints at hw_params.
snd_usb_endpoint_configure() is a single function that does the full
setup, and it's called from both PCM hw_params and prepare callbacks.
Although the EP setup at the prepare phase is usually skipped (by
checking need_setup flag), it may be still effective in some cases
like suspend/resume that requires the interface setup again.
As it's a full and single setup, the invocation of
snd_usb_endpoint_configure() includes not only the USB interface setup
but also the buffer release and allocation. OTOH, doing the buffer
release and re-allocation at PCM prepare phase is rather superfluous,
and better to be done only in the hw_params phase.
For those optimizations, this patch splits the endpoint setup to two
phases: snd_usb_endpoint_set_params() and snd_usb_endpoint_prepare(),
to be called from hw_params and from prepare, respectively.
Note that this patch changes the driver operation slightly,
effectively moving the USB interface setup again to PCM prepare stage
instead of hw_params stage, while the buffer allocation and such
initializations are still done at hw_params stage.
And, the change of the USB interface setup timing (moving to prepare)
gave an interesting "fix", too: it was reported that the recent
kernels caused silent output at the beginning on playbacks on some
devices on Android, and this change casually fixed the regression.
It seems that those devices are picky about the sample rate change (or
the interface change?), and don't follow the too immediate rate
changes.
Meanwhile, Android operates the PCM in the following order:
- open, then hw_params with the possibly highest sample rate
- close without prepare
- re-open, hw_params with the normal sample rate
- prepare, and start streaming
This procedure ended up the hw_params twice with different rates, and
because the recent kernel did set up the sample rate twice one and
after, it screwed up the device. OTOH, the earlier kernels didn't set
up the USB interface at hw_params, hence this problem didn't appear.
Now, with this patch, the USB interface setup is again back to the
prepare phase, and it works around the problem automagically.
Although we should address the sample rate problem in a more solid
way in future, let's keep things working as before for now.

When the delayed registration is specified via either delayed_register
option or the quirk, we delay the invocation of snd_card_register()
until the given interface. But if a wrong value has been set there
and there are more interfaces over the given interface number,
snd_card_register() call would be missing for those interfaces.
This patch catches up those missing calls by fixing the comparison of
the interface number. Now the call is skipped only if the processed
interface is less than the given interface, instead of the exact
match.

The info message that was added in the commit a4aad5636c ("ALSA:
usb-audio: Inform devices that need delayed registration") is actually
useful to know the need for the delayed registration. However, it
turned out that this doesn't catch the all cases; namely, this warned
only when a PCM stream is attached onto the existing PCM instance, but
it doesn't count for a newly created PCM instance. This made
confusion as if there were no further delayed registration.
This patch moves the check to the code path for either adding a stream
or creating a PCM instance. Also, make it simpler by checking the
card->registered flag instead of querying each snd_device state.

So if the platform component is not ready at that time, then the

is empty, the sound card can't be used.
As there is defer probe checking for cpu dai component, then register

It's been reported that there is a possible data-race accessing to the
global card_requested[] array at ALSA sequencer core, which is used
for determining whether to call request_module() for the card or not.
This data race itself is almost harmless, as it might end up with one
extra request_module() call for the already loaded module at most.
But it's still better to fix.
This patch addresses the possible data race of card_requested[] and
client_requested[] arrays by replacing them with bitmask.
It's an atomic operation and can work without locks.

Merge series from Takashi Iwai <tiwai@suse.de>:
This is a series of patches to address the issues on nau8xxx codecs
I've stumbled upon while dealing with a bug report for Steam Deck.
Most of them are to implement the missing hw constraint for rate
restrictions while one patch is to fix the semaphore unbalance in
nau8824 driver.
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
There is still a chance to end up with a client driver selected as built in
while the core SOF is as module.
Fix this by making the client drivers depend on SND_SOC_SOF.
A recent change in clang strengthened its -Wbitfield-constant-conversion
to warn when 1 is assigned to a 1-bit signed integer bitfield, as it can
only be 0 or -1, not 1:
sound/soc/atmel/mchp-spdiftx.c:505:20: error: implicit truncation from 'int' to bit-field changes value from 1 to -1 [-Werror,-Wbitfield-constant-conversion]
dev->gclk_enabled = 1;
^ ~
1 error generated.
The actual value of the field is never checked, just that it is not
zero, so there is not a real bug here. However, it is simple enough to
silence the warning by making the bitfield unsigned, which matches the
mchp-spdifrx driver.

ALSA OSS sequencer refers to a global variable max_midi_devs at
creating a new port, storing it to its own field. Meanwhile this
variable may be changed by other sequencer events at
snd_seq_oss_midi_check_exit_port() in parallel, which may cause a data
race.
OTOH, this data race itself is almost harmless, as the access to the
MIDI device is done via get_mdev() and it's protected with a refcount,
hence its presence is guaranteed.
Though, it's sill better to address the data-race from the code sanity
POV, and this patch adds the proper spinlock for the protection.

nau8540 driver restricts the sample rate with over sampling rate, but
currently it barely bails out at hw_params with -EINVAL error (with a
kernel message); this doesn't help for user-space to recognize which
rate can be actually used.
This patch introduces the proper hw constraint for adjusting the
available range of the sample rate depending on the OSR setup, as well
as some code cleanup, for improving the communication with
user-space. Now applications can know the valid rate beforehand and
reduces the rate appropriately without errors.

The semaphore of nau8824 wasn't properly unlocked at some error
handling code paths, hence this may result in the unbalance (and
potential lock-up). Fix them to handle the semaphore up properly.

When the first DMIC recording is power down, mtkaif_dmic will be reset.
This will cause configuration error in the second DMIC recording. So do
not reset mtkaif_dmic except in "MTKAIF_DMIC Switch" kcontrol.
