Commit 03cef710 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'sound-4.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Here are a bunch of fixes as you can see in diffstat.

  One core change in ASoC is about the unexpected unbinding error, and
  another about debugfs cleanup.

  The rest are wide-spread driver-specific fixes: a series of LINE6 USB
  fixes, a HD-audio quirk, and various ASoC fixes including OMAP boot
  fixes and Intel SKL fixes"
