Subject: ASoC: ak4642: prevent un-necessary changes to SG_SL1
From: Phil Edworthy <phil.edworthy@xxxxxxxxxxx>
commit 7b5bfb82882b9b1c8423ce0ed6852ca3762d967a upstream.
If you record the sound during playback,
the playback sound becomes silent.
Modify so that the codec driver does not clear
SG_SL1::DACL bit which is controlled under widget
