since commit 57e6dae108 ("ALSA: usb-audio: do not trust too-big
wMaxPacketSize values"), the expected packetsize is always limited
to nominal + 25%. It was discovered, that some devices (Android audio
accessory) have a much higher jitter in used packetsizes than 25%
which would result in BABBLE condition and dropping of packets.
A better solution is so assume the jitter to be the nominal packetsize:
-one nearly empty packet followed by a almost 150% sized one.
V2: changed to assume max frequency is +50 of nominal packetsize.

Some of userland applications call 'snd_pcm_hw_params()' and
'snd_pcm_hw_prepare()' sequentially, which means 'snd_pcm_hw_prepare()'
is called twice and the second 'snd_pcm_hw_prepare()' is called in
'SNDRV_PCM_STATE_PREPARED' state.
Some devices are not able to manage this and they will stop playback
if the sample rate will be configured several times over USB protocol.

Kernel panic - not syncing: Fatal exception in interrupt
There is a race between retire_capture_urb() and stop_endpoints().
The latter is called at stopping the stream and it sets some endpoint
fields to NULL. But its call is asynchronous, thus the pending
complete callback might get called after these NULL clears, and it
leads the NULL dereference like the above.
The fix is to move the NULL clearance after the synchronization,
i.e. wait_clear_urbs(). This is called at prepare and hw_free
callbacks, so it's assured to be called before the restart of the
stream or the release of the stream.
Also, while we're at it, put the EP_FLAG_RUNNING flag check at the
beginning of snd_complete_urb() to skip the pending complete after the
stream is stopped.

More and more pin configurations have been adding to the pin quirk
table, lots of them are only different from assoc and seq, but they
all apply to the same QUIRK_FIXUP, if we don't compare assoc and seq
when matching pin configurations, it will greatly reduce the pin
quirk table size.

This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver
to use work instead of kthread in a loop. The work is lighter and
easier to control than kthread, in general.
Instead of a loop with the explicit sleep, we do simply
delayed-schedule the work. At suspend/resume callbacks, the work is
canceled and restarted, respectively.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
The EMU1010 support in emu10k1 driver has two request_firmware()
calls, one for the main board and one for the dock. Both call
patterns are fairly similar, and we can simplify it by introducing a
helper function and a table instead of the open switch/case.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
The emu1010_firmware_thread() checks the previous dock status, but a
wrong register is recorded as the last status when the dock is plugged
in. Usually this isn't a big issue since this value gets overwritten
by the next loop after one second. But when a dock is unplugged
immediately after plugging, it means essentially missing undock
handling.
This patch addresses it by remembering the correct register value.

The commit [1a3f099101b8: ALSA: hda - Fix surround output pins for
ASRock B150M mobo] introduced a fixup of pin configs for ASRock
mobos to fix the surround outputs. However, this overrides the pin
configs of the mic pins as if they are outputs-only, effectively
disabling the mic inputs. Of course, it's a regression wrt mic
functionality.
Actually the pins 0x18 and 0x1a don't need to be changed; we just need
to disable the bogus pins 0x14 and 0x15. Then the auto-parser will
pick up mic pins as switchable and assign the surround outputs there.
This patch removes the incorrect pin overrides of NID 0x18 and 0x1a
from the ASRock fixup.
