[alsa-devel] [PATCH 0/3] ASoC: max98090: revert invalid fixes

[Tzung-Bi Shih]

A critical side-effect was observed along with the commit 62d5ae4cafb7
("ASoC: max98090: save and restore SHDN when changing sensitive registers").

When keep playing something,
(e.g. sox -n -t s16 -r 48000 -c 2 - synth sine 440 vol 0.1 | \
      aplay -D hw:0,0 -f S16_LE -r 48000 -c 2)

the recorded sound has chance to break (clipping).
(e.g. while [ 1 ]; do
        arecord -q -f S16_LE -d 2 -r 48000 -c 2 test.raw \
	sox -t s16 -r 48000 -c 2 test.raw  -n stat \
	...
      done)

The series reverts all related commits.
I feel really sorry for the whole mess.
