sound fixes for 4.6-rc5

Browse source 
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.
