Revision a1e9185d20b56af04022d2e656802254f4ea47eb authored by Linus Torvalds on 02 December 2022, 23:40:35 UTC, committed by Linus Torvalds on 02 December 2022, 23:40:35 UTC 
Merge tag 'sound-6.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
 
Pull sound fixes from Takashi Iwai:
 "Likely the last piece for 6.1; the only significant fixes are ASoC
  core ops fixes, while others are device-specific (rather minor) fixes
  in ASoC and FireWire drivers.

  All appear safe enough to take as a late stage material"

* tag 'sound-6.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: dice: fix regression for Lexicon I-ONIX FW810S
  ASoC: cs42l51: Correct PGA Volume minimum value
  ASoC: ops: Correct bounds check for second channel on SX controls
  ASoC: tlv320adc3xxx: Fix build error for implicit function declaration
  ASoC: ops: Check bounds for second channel in snd_soc_put_volsw_sx()
  ASoC: ops: Fix bounds check for _sx controls
  ASoC: fsl_micfil: explicitly clear CHnF flags
  ASoC: fsl_micfil: explicitly clear software reset bit
