We fixed the bug introduced by the patch for managing the shared
clocks at the commit 809f44a0cc ("ALSA: usb-audio: Clear fixed clock
rate at closing EP"), but it was merely a workaround. By this change,
the clock reference rate is cleared at each EP close, hence the still
remaining EP may need a re-setup of rate unnecessarily.
This patch introduces the proper refcounting for the clock reference
object so that the clock setup is done only when needed.

This is a second attempt to fix the bug appearing on Android with the
recent kernel; the first try was ff878b408a and reverted at commit
79764ec772.
The details taken from the v1 patch:
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.
***
What's new in the take#2 patch:
- The regression caused by the v1 patch (bko#216500) was due to the
missing check of need_setup flag at hw_params. Now the check is
added, and the snd_usb_endpoint_set_params() call is skipped when
the running EP is re-opened.
- There was another bug in v1 where the clock reference rate wasn't
updated at hw_params phase, which may lead to a lack of the proper
hw constraints when an application doesn't issue the prepare but
only the hw_params call. This patch fixes it as well by tracking
the clock rate change in the prepare callback with a new flag
"need_update" for the clock reference object, just like others.
- The configure_endpoints() are simplified and folded back into
snd_usb_pcm_prepare().

The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but
releases it before calling snd_hdac_stream_release() where the bus
reg_lock is taken again.
This creates a timing window where the link stream release could test
an invalid 'opened' boolean status and fail to recouple the host and
link parts.
Fix by exposing a locked version of snd_hdac_stream_release() and use
it without releasing the spinlock.

The logic is needlessly complicated, the basic rule is:
The host streams can be found by checking the 'opened' boolean.
The link streams can be found by checking the 'link_locked' boolean.
Once a stream is found, it can be unconditionally decoupled. The
snd_hdac_ext_stream_decouple_locked() routine will make sure the
register status is modified as needed and the 'decoupled' boolean set.

The recent fix in commit 6392dcd1d0 ("ALSA: usb-audio: Register card
at the last interface") tried to delay the card registration until the
last found interface is probed. It assumed that the probe callback
gets called for those later interfaces, but it's not always true; as
the driver loops over the descriptor and probes the matching ones,
it's not separately called via multiple probe calls. This results in
the missing card registration, i.e. no sound device.
For addressing this problem, replace the check whether the last
interface is processed with usb_interface_claimed() instead of the
comparison with the probe interface number.

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.

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.

When put_device() is called in another function it's hard to realize
that and easy to "fix" the code in a wrong way. Instead, move
put_device() to be in the same scope as get_device(), so we prevent
appearance of any attempts to "fix" the code.

The recent fix for IDT codecs to keep the power up while the beep is
enabled can be better integrated into the beep helper code.
This patch cleans up the code with refactoring.
Fixes: 414d38ba87 ("ALSA: hda/sigmatel: Keep power up while beep is enabled")

The USB-audio driver matches per interface, and as default, it
registers the card instance at the very first instance. This can be a
problem for the devices that have multiple interfaces to be probed, as
the udev rule isn't applied properly for the later appearing
interfaces. Although we introduced the delayed_register option and
the quirks for covering those shortcomings, it's nothing but a
workaround for specific devices.
This patch is an another attempt to fix the problem in a more generic
way. Now the driver checks the whole USB device descriptor at the
very first time when an interface is attached to a sound card. It
looks at each matching interface in the descriptor and remembers the
last matching one. The snd_card_register() is invoked only when this
last interface is probed.
After this change, the quirks for the delayed registration become
superfluous, hence they are removed along with the patch. OTOH, the
delayed_register option is still kept, as it might be useful for some
corner cases (e.g. a special driver overtakes the interface probe from
the standard driver, and the last interface probe may miss).
