Merge tag 'sound-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "The amount of changes is smaller at this round (what a surprise), but
  lots of activity is seen. Most of changes are about ASoC driver
  development, especially Intel platforms. Here are some highlights:

  General:
   - Replace all tasklet usages with other alternatives
   - Cleanup of the ASoC error unwinding code
   - Fixes for trivial issues caught by static checker
   - Spell fixes allover the places

  ALSA Core:
   - Lockdep fix for control devices
   - Fix for potential OSS sequencer mutex stalls

  HD-audio and USB-audio:
   - SoundBlaster AE-7 support
   - Changes in quirk table for the rename handling
   - Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.

  ASoC:
   - Lots of updates for Intel SOF and SoundWire enablement
   - Replacement of the DSP driver for some older x86 systems; the new
     code was written from scratch, better maintenance expected
   - Helpers for parsing auxiluary devices from the device tree
   - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
     Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas
     Instruments J721E, TAS2110, TAS2564 and TAS2764"
