We must do it this way, because e.g. POD X3 won't play any sound unless
the host listens on the bulk EP, so we cannot export it only via libusb.
The driver currently doesn't use the bulk EP messages in other way,
in future it could e.g. sense/modify volume(s).

This includes audio in/out and basic initialization via control EP (emulates
what original driver does). The initialization is done similarly to original
POD, firmware and serial IDs are read and exported via sysfs.

E.g. POD X3 seems to require playback data to be sent to it to generate

The newly added rt5663 codec driver introduces a couple of warnings
when built with -Wmaybe-uninitialized:
codecs/rt5663.c: In function 'rt5663_set_tdm_slot':
codecs/rt5663.c:2680:2: error: 'reg' may be used uninitialized in this function [-Werror=maybe-uninitialized]

codecs/rt5663.c:2596:2: error: 'mask' may be used uninitialized in this function [-Werror=maybe-uninitialized]
We can avoid those warnings by always returning an error
from the switch() statements instead of falling through
with an uninitialized variable when we hit an unexpected
case.

ASoC: Fixes for v4.8
A clutch of fixes for v4.8. These are mainly driver specific, the most
notable ones being those for OMAP which fix a series of issues that
broke boot on some platforms there when deferred probe kicked in.
There's also one core fix for an issue when unbinding a card which for
some reason had managed to not manifest until recently.

According to the datasheets of Realtek ALC5658 (Rev. 0.9)
and ALC5659 (Rev. 0.13), the "IRQ Control 4" register is
located at MX-00BAh while the "IRQ control 5" register is
at MX-00BBh.
There is no "IRQ Control 6" register in the datasheets but
it is supposed to be behind the "IRQ Control 5" register.
So this patch corrects these addresses.

The workqueue "dac33_wq" queues a single work item &dac33->work and
hence doesn't require ordering. Also, it is not being used on a memory
reclaim path. Hence, it has been converted to use system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
The work item has been flushed in dac33_soc_remove to ensure that
there are no pending tasks while disconnecting the driver.

Currently the driver code assumes that MCLK will be present during
the procedure, or if it has control of MCLK then it can make sure
it's enabled. Some platforms however do not provide MCLK to the
driver in this way, and will not leave MCLK enabled when Codec is
in STANDBY state.
This patch adds support for the HP detect procedure when running
from the device's internal oscillator, to ensure all platforms
can make use of this feature correctly.

Realtek codec driver expects an implicit rule where either the codec
SSID or the pincfg NID 0x1d contains the some information encoded in
some bits. One of the expected information is there is the
availability of PC beep, and the driver doesn't build up the PC beep
control if this is *supposed* to be disabled there.
Meanwhile, Lenovo doesn't seem to follow this requirement (yes it's
non-standard after all), and the BIOS sets just the normal SSID and
the pincfg values. This resulted in the lack of PC beep on a few
machines, purely with a lucky or unlucky number. It didn't bother
most people, but some people still demand the PC beep, as found in bug
reports.
This patch just adds the fixup chain to Lenovo machines to skip the
SKU checks. Then the beep control will show up in the mixer, and user
can still decide to enable / disable it via the standard mixer
interface.

When a seq-virmidi driver is initialized, it registers a rawmidi
instance with its callback to create an associated seq kernel client.
Currently it's done throughly in rawmidi's register_mutex context.
Recently it was found that this may lead to a deadlock another rawmidi
device that is being attached with the sequencer is accessed, as both
open with the same register_mutex. This was actually triggered by
syzkaller, as Dmitry Vyukov reported:

The fix is to simply move the registration parts in
snd_rawmidi_dev_register() to the outside of the register_mutex lock.
The lock is needed only to manage the linked list, and it's not
necessarily to cover the whole initialization process.

Although a similar issue was spotted and a fix patch was merged in
commit [6b760bb2c63a: ALSA: timer: fix division by zero after
SNDRV_TIMER_IOCTL_CONTINUE], it seems covering only a part of
iceberg.
In this patch, we fix the issue a bit more drastically. Basically the
continue of an uninitialized timer is supposed to be a fresh start, so
we do it for user timers. For the direct snd_timer_continue() call,
there is no way to pass the initial tick value, so we kick out for the
uninitialized case.

When the stream is in suspended state some applications wait
on "Stream Pipe Error" in response to snd_pcm_avail call to
resume the stream.
In the current implementation snd_pcm_avail() returns zero
when the stream is in suspended state. This causes application
to enter in infinite loop for frames to be available.
"Stream pipe Error" code is getting returned for read/write
call when the stream is in suspended state. Similarly update
snd_pcm_avail to return -ESTRPIPE.

fix issue reported by 0-Day with randconfig
The commit a68bc0d43e1b
("ASoC: Intel: Atom: auto-detection of Baytrail-CR")
added a dependency on IOSF_MBI. The code used the IS_ENABLED macro
to check for this dependency but this is not enough in case the SST
driver is built-in. This could be fixed with IS_REACHABLE but
Baytrail-CR would not be detected depending on combinations of options
Add dependency in Kconfig to solve this for good

Theta/lambda is used to give the fractional portion of the FLL
frequency multiplication. When the synchroniser is active the
reference path lambda value is hard coded in the hardware to
65536. This patch corrects the handling of theta such that it
is scaled to match this denominator, when the synchroniser is
active.
