Merge tag 'sound-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"Again a relatively calm week without surprise: most of fixes are about
HD-audio, including fixes for Cirrus codec regression and a race over
regmap access. Although both change are slightly unintuitive, the
risk of further breakage is quite low, I hope.
Other than that, all the rest are trivial"
