Merge tag 'sound-5.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"The only common change is the regression fix of the previous PCM fix
patch for managed buffers while the rest are usual suspects, USB-audio
and HD-audio device-specific quirks.
The change for UAC2 clock validation workaround became a bit big, but
the changes are fairly straightforward"
