Pull sound fixes from Takashi Iwai:
 "A collection of small fixes:

   - A few regression fixes (PCM core fixes, USB-audio fixes)

   - Follow up fixes for the USB-audio mixer changes in this cycle

   - A long-standing ALSA sequencer race bug fix

   - Usual device-specific quirks for HD- and USB-audio"
