    Merge tag 'sound-4.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
    
    Pull sound fixes from Takashi Iwai:
     "It's our tradition to get a high volume of fixes late at rc7: this
      time, X32 ABI breakage was found and this resulted in a high number
      LOCs.  The necessary changes to ALSA core codes were fairly
      straightforward, and more importantly, they are specific to X32, thus
      should be safe to apply.
    
      Other than that, rather a collection of small fixes:
       - Removal of the code that blocks too long at closing the OSS
         sequencer client (which was spotted by syzkaller, unsurprisingly)
       - Fixes races at HD-audio HDMI i915 audio binding
       - a few HDSP/HDPM zero-division fixes
       - Quirks for HD-audio and USB-audio as usual"
