3.5.7.2 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Daniel J Blueman <redacted> commit 16337e028a6dae9fbdd718c0d42161540a668ff3 upstream. Correctly enable the digital microphones with the right bits in the right coeffecient registers on Cirrus CS4206/7 codecs. It also prevents misconfiguring ADC1/2. This fixes the digital mic on the Macbook Pro 10,1/Retina.
