Merge tag 'sound-fix-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
"This contains a one-liner change that has a significant impact:
disabling the build of OSS. It's been unmaintained for long time, and
we'd like to drop the stuff. Finally, as the first step, stop the
build. Let's see whether it works without much complaints.

Other than that, there are two small fixes for HD-audio"
