Merge tag 'sound-4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Things got calmed down for rc6, as it seems, and we have only a few
  HD-audio fixes at this time: a fix for Skylake codec probe errors, a
  fix for missing interrupt handling, and a few Dell and HP quirks"

* tag 'sound-4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - Loop interrupt handling until really cleared
  ALSA: hda - Fix headset support and noise on HP EliteBook 755 G2
  ALSA: hda - Fixup speaker pass-through control for nid 0x14 on ALC225
  ALSA: hda - Fixing background noise on Dell Inspiron 3162
  ALSA: hda - Apply clock gate workaround to Skylake, too
