[PATCH 1/2] ASoC: tas2562: Drop conflicting set_bias_level power setting

From: Martin Povišer
Date: Thu Aug 25 2022 - 10:22:55 EST


The driver is setting the PWR_CTRL field in both the set_bias_level
callback and on DAPM events of the DAC widget (and also in the
mute_stream method). Drop the set_bias_level callback altogether as the
power setting it does is in conflict with the other code paths.

(This mirrors commit c8a6ae3fe1c8 ("ASoC: tas2770: Drop conflicting
set_bias_level power setting") which was a fix to the tas2770 driver.)
