Pull sound fixes from Takashi Iwai:
 "Again a collection of small fixes, mostly for device-specific ones.

  The only big LOC is about the removal of pretty old dead code in
  ab8500 codec driver, while the rest all nice small changes.

  Core / API:
   - Fix race in deferred fasync state checks
   - Fix UMP group filtering in sequencer

  ASoC:
   - cs35l56: fixes for driver cleanup and error paths
   - tas2764/2770: workaround for bogus temperature readings
   - wm_adsp: fixes for firmware unit tests
   - amd-yc: more DMI quirks for laptops
   - Minor fixes for fsl_xcvr and spacemit

  HD-Audio:
   - Mute LED and speaker quirks for HP, Lenovo, and Xiaomi laptops

  USB-audio:
   - New device-specific quirks (Motu, JBL, AlphaTheta, Razer)
   - Fix of MIDI2 playback on resume

  Others:
   - Firewire-tascam control event fix
   - Minor cleanups and fixes for sparc/dbri and pcmtest"
