The usb-audio driver detects XRUN at its complete callback, but the
actual code to trigger PCM XRUN is commented out because it caused
deadlock in the past. This patch revives the PCM trigger properly.
It resulted in more than just enabling snd_pcm_stop(), but it had to
deduce the PCM substream with proper NULL checks and holds the stream
lock around the call.

Some state changes (e.g. snd_pcm_stop()) sets the runtime state after

Although the possibility is low, we should set the state before the

the DAC power-down bit. This widget is connected to both the DAC and a newly
introduced VMID widget. This makes sure that the DAC power-down bit is not
set as long as a audio sink is connected to the DAC output. At the same time

This comes from the fact that usb-audio driver may receive the
disconnect callback multiple times, per each usb interface. When a
device has both audio and midi interfaces, it gets called twice, and
currently the driver tries to release resources at the last call.
At this point, the first parent interface has been already deleted,
thus deleting a child of the first parent hits such a warning.
For fixing this problem, we need to call snd_card_disconnect() and
cancel pending operations at the very first disconnect while the
release of the whole objects waits until the last disconnect call.

DPCM can update the FE/BE connection states totally asynchronously
from the FE's PCM state. Most of FE/BE state changes are protected by
mutex, so that they won't race, but there are still some actions that
are uncovered. For example, suppose to switch a BE while a FE's
stream is running. This would call soc_dpcm_runtime_update(), which
sets FE's runtime_update flag, then sets up and starts BEs, and clears
FE's runtime_update flag again.
When a device emits XRUN during this operation, the PCM core triggers
snd_pcm_stop(XRUN). Since the trigger action is an atomic ops, this
isn't blocked by the mutex, thus it kicks off DPCM's trigger action.
It eventually updates and clears FE's runtime_update flag while
soc_dpcm_runtime_update() is running concurrently, and it results in
confusion.
Usually, for avoiding such a race, we take a lock. There is a PCM
stream lock for that purpose. However, as already mentioned, the
trigger action is atomic, and we can't take the lock for the whole
soc_dpcm_runtime_update() or other operations that include the lengthy
jobs like hw_params or prepare.
This patch provides an alternative solution. This adds a way to defer
the conflicting trigger callback to be executed at the end of FE/BE
state changes. For doing it, two things are introduced:
- Each runtime_update state change of FEs is protected via PCM stream
lock.
- The FE's trigger callback checks the runtime_update flag. If it's
not set, the trigger action is executed there. If set, mark the
pending trigger action and returns immediately.
- At the exit of runtime_update state change, it checks whether the
pending trigger is present. If yes, it executes the trigger action
at this point.

The usb-audio probe and disconnect functions have been split just for
adapting the (new!) API at 2.5 kernel time. We left them until now,
partly because we wanted to build with the pretty old kernels in the
external alsa-driver tree. But the support of such old kernels has
been longly stopped, so it's good time to clean up this mess.
One good point by this cleanup is that now the probe function returns
a proper error code instead of only -EIO.

This patch adds a new proc entry for PCM substreams to inject an
XRUN. When a PCM substream is running and any value is written to its
xrun_injection proc file, the driver triggers XRUN. This is a useful
feature for debugging XRUN and error handling code paths.
Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is
set.

ALSA PCM core has a mechanism tracking the PCM hwptr updates for
analyzing XRUNs. But its log is limited (up to 10) and its log output
is a kernel message, which is hard to handle.
In this patch, the hwptr logging is moved to the tracing
infrastructure instead of its own. Not only the hwptr updates but
also XRUN and hwptr errors are recorded on the trace log, so that user
can see such events at the exact timing.
The new "snd_pcm" entry will appear in the tracing events:
# ls -F /sys/kernel/debug/tracing/events/snd_pcm
enable filter hw_ptr_error/ hwptr/ xrun/
The hwptr is for the regular hwptr update events. An event trace
looks like:
aplay-26187 [004] d..3 4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384
"POS" shows the hwptr update by the explicit position update call and
"IRQ" means the hwptr update by the interrupt,
i.e. snd_pcm_period_elapsed() call. The "pos" is the passed
ring-buffer offset by the caller, "old" is the previous hwptr, "base"
is the hwptr base position, "period" and "buf" are period- and
buffer-size of the target PCM substream.
(Note that the hwptr position displayed here isn't the ring-buffer
offset. It increments up to the PCM position boundary.)
The XRUN event appears similarly, but without "pos" field.
The hwptr error events appear with the PCM identifier and its reason
string, such as "Lost interrupt?".
The XRUN and hwptr error reports on kernel message are still left, can
be turned on/off via xrun_debug proc like before. But the bit 3, 4, 5
and 6 bits of xrun_debug proc are dropped by this patch. Also, along
with the change, the message strings have been reformatted to be a bit
more consistent.
Last but not least, the hwptr reporting is enabled only when
CONFIG_SND_PCM_XRUN_DEBUG is set.
