This is essentially a partial revert of the commit [b1920c2110:
'ALSA: hda - Enable runtime PM on Panther Point']. There was a bug
report showing the HD-audio bus hang during runtime PM on HP Spectre
XT.

When a PCM draining is performed to an empty stream that has been
already in PREPARED state, the current code just ignores and leaves as
it is, although the drain is supposed to set all such streams to SETUP
state. This patch covers that overlooked case.

A part of these drivers, especially BeBoB driver, are programmed to wait
some events. Thus the drivers should not destroy any data in .remove()
context.
This commit moves some destructors from 'struct fw_driver.remove()' to
'struct snd_card.private_free()' to shutdown safely.

Currently stream destructor in each driver has a problem to be called in
a context in which sound card object is released, because the destructors
call amdtp_stream_pcm_abort() and touch PCM runtime data.
The PCM runtime data is destroyed in application's context with
snd_pcm_close(), on the other hand PCM substream data is destroyed after
sound card object is released, in most case after all of ALSA character
devices are released. When PCM runtime is destroyed and PCM substream is
remained, amdtp_stream_pcm_abort() touches PCM runtime data and causes
Null-pointer-dereference.
This commit changes stream destructors and allows each driver to call
it after releasing runtime.

AMDTP helper functions increment/decrement reference counter for an

Fireworks and Dice drivers try to touch instances of FireWire unit after
sound card object is released, while references to the unit is decremented
in .remove(). When unplugging during streaming, sound card object is
released after .remove(), thus Fireworks and Dice drivers causes GPF or
Null-pointer-dereferencing to application processes because an instance of
FireWire unit was already released.
This commit adds reference-counting for FireWire unit in drivers to allow
them to touch an instance of FireWire unit after .remove(). In most case,
any operations after .remove() may be failed safely.

The sign for microsecond (U+0085, MICRO SIGN) was encoded to '0x c2 b5'
by UTF-8 character encoding scheme. But the byte sequence was converted
to '0x c3 82 c2 b5' in a previous commit. As a result, the byte
sequence cannot represent microsecond sign in UTF-8 or ASCII. This
may confuse developers.
This commit replaces the sign to string expression with 'microseconds'
to purge superfluous troubles.

Adds a quirk to disable the check that the sample rate has been set correctly, as the Lifecam does not support getting the sample rate.
This means that we don't need to wait for the USB timeout when attempting to get the sample rate. Waiting for the timeout causes problems in some applications, which give up on the device acquisition process before it has had time to complete, resulting in no sound.

The device indicates the result of a read/write operation by making the

ready immediately, though, so the driver is currently slamming the

The first URBs are submitted during the prepare stage. When .trigger is
called, the ALSA core saves a trigger tstamp that doesn't correspond to
the actual time when the samples are submitted. The trigger_tstamp is
now updated when the first data are submitted to avoid any time offsets.
A usb-specific trigger_tstamp_pending_update flag is used for now,
at some point the flag would need to move to the ALSA core, USB
is not the only interface where silent block transfers are programmed
as part of the prepare stage, with actual data enabled when .trigger

The problem here is that we check:
if (dev >= SNDRV_CARDS)
Then we increment "dev".
if (!joystick_port[dev++])
Then we use it as an offset into a array with SNDRV_CARDS elements.
if (!request_region(joystick_port[dev], 8, "Riptide gameport")) {
This has 3 effects:
1) If you use the module option to specify the joystick port then it has
to be shifted one space over.
2) The wrong error message will be printed on failure if you have over
32 cards.
3) Static checkers will correctly complain that are off by one.

ASoC: Final updates for v3.20
A few more updates for v3.20 that have accumilated over the second half
of last week. One new (relatively simple) driver for the Maxim
max98357a and some other driver specific fixes and enhancements. I did
apply a few patches that haven't been in -next just now before sending
this, all fixes except for one simple device ID addition patch.
