Merge tag 'sound-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "Hopefully the last PR for 6.11, at least for this level of amount. In addition to the usual HD-audio quirks, there are more changes in ASoC, but all look small and device-specific fixes, and nothing stands out.
