Merge tag 'sound-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Again a relatively calm week without surprise: most of fixes are about
  HD-audio, including fixes for Cirrus codec regression and a race over
  regmap access.  Although both change are slightly unintuitive, the
  risk of further breakage is quite low, I hope.

  Other than that, all the rest are trivial"

* tag 'sound-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - Fix possible race on regmap bypass flip
  ALSA: pcxhr: Fix missing mutex unlock
  ALSA: hda - add PCI ID for Intel Broxton-T
  ALSA: hda - Keep powering up ADCs on Cirrus codecs
  ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m
  ALSA - hda: hdmi check NULL pointer in hdmi_set_chmap
  ALSA: hda - Don't trust the reported actual power state
