Merge tag 'sound-3.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Here includes a few patchset for fixing mostly HD-audio issues in
  addition to a patch assuring the compress API bytes alignment and a
  fix for the die-hard existing race condition at USB-audio
  disconnection.  The volume looks big in Realtek HD-audio code, but
  it's just a translation of the fixup tables, and the actual changes
  are rather trivial"

* tag 'sound-3.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - restore BCLK M/N values when resuming HSW/BDW display controller
  ALSA: usb-audio: Fix races at disconnection and PCM closing
  ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13
  ALSA: hda - Make the pin quirk tables use the SND_HDA_PIN_QUIRK macro
  ALSA: hda - Make a SND_HDA_PIN_QUIRK macro
  ALSA: hda - Add pin quirk for Dell XPS 15
  ALSA: hda - hdmi: call overridden init on resume
  ALSA: hda - Fix usage of "model" module parameter
  ALSA: compress: fix the struct alignment to 4 bytes
