Subject: [ 013/171] ALSA: HDA: Fix digital microphone on CS420x

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel J Blueman <daniel@...ra.org>

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.
