Merge tag 'sound-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "A relatively calm release at this time, and no massive code changes
  are found in the stats, while a wide range of code refactoring and
  cleanup have been done.

  Note that this update includes the tree-wide trivial changes for
  dropping the return value from ISA remove callbacks, too.

  Below lists up some highlight:

  ALSA Core:
   - Support for the software jack injection via debugfs
   - Fixes for sync_stop PCM operations

  HD-audio and USB-audio:
   - A few usual HD-audio device quirks
   - Updates for Tegra HD-audio
   - More quirks for Pioneer and other USB-audio devices
   - Stricter state checks at USB-audio disconnection

  ASoC:
   - Continued code refactoring, cleanup and fixes in ASoC core API
   - A KUnit testsuite for the topology code
   - Lots of ASoC Intel driver Realtek codec updates, quirk additions
     and fixes
   - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
     nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
   - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers

  Others:
   - Drop return value from ISA driver remove callback
   - Cleanup with DIV_ROUND_UP() macro
   - FireWire updates, HDSP output loopback support"
