ALSA: line6: Add delay before reading status
The device indicates the result of a read/write operation by making the
status available on a subsequent request from the driver. This is not
ready immediately, though, so the driver is currently slamming the
device with hundreds of pointless requests before getting the expected
response. Add a two millisecond delay before each attempt. This is
approximately the behavior observed with version 4.2.7.1 of the Windows
driver.

ASoC: Intel: Clean data after SST fw fetch

ALSA: usb: update trigger timestamp on first non-zero URB submitted
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
is called.
ALSA: pcm: allow for trigger_tstamp snapshot in .trigger
Don't use generic snapshot of trigger_tstamp if low-level driver or
hardware can get a more precise value for better audio/system time
synchronization.
timestamp in RUNNING mode is already taken in update_hw_ptr routine,
getting a new timestamp introduces offset between hw_ptr, audio_tstamp
and system time
Add else condition to read timestamp as fallback and only when
enabled

ALSA: off by one bug in snd_riptide_joystick_probe()
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.
