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
