Merge tag 'sound-4.1-rc8' of git://git.kernel.org/pub/scm/linux/kerne…

…l/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Most of commits are regression fixes for HD-audio: a few corner case
  fixes for regmap transition, and i915 binding issues.

  In addition, a quirk for another USB-audio device supporting DSD"

* tag 'sound-4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - Abort the probe without i915 binding for HSW/BDW
  ALSA: hda - Re-add the lost fake mute support
  ALSA: hda - Continue probing even if i915 binding fails
  ALSA: hda - Don't actually write registers for caps overwrites
  ALSA: hda - fix number of devices query on hotplug
  ALSA: usb-audio: add native DSD support for JLsounds I2SoverUSB
