Subject: ALSA: hda - Don't override ADC definitions for ALC codecs
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=dd704698f56c1451fc9c5daadcd6e3a089de2c40;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

ALSA: hda - Don't override ADC definitions for ALC codecs

ALC269 and ALC861-VD parsers override the ADC definitions
unconditionally without checking the spec definition.  This causes
the problem when any inconsistent ADC is set up in the device quirk
(like ALC272 with digital-mic).

This patch avoids the overriding by adding the proper checks.
