Merge tag 'sound-fix-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"The previous pull request introduced a few WARN_ON() for Intel
HD-audio HDMI. Indeed it caught bugs, and now users get annoyed. So
this request came up: a collection of small fixes to paper over the
inconsistencies on (mostly) old Intel chipsets.
In addition, a trivial USB-audio quirk is included, too"
