Merge tag 'sound-5.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "One significant regression fix is for HD-audio buffer preallocation.
  In 5.6 it was set to non-prompt for x86 and forced to 0, but this
  turned out to be problematic for some applications, hence it gets
  reverted. Distros would need to restore CONFIG_SND_HDA_PREALLOC_SIZE
  value to the earlier values they've used in the past.

  Other than that, we've received quite a few small fixes for HD-audio
  and USB-audio. Most of them are for dealing with the broken TRX40
  mobos and the runtime PM without HD-audio codecs"
