I don't think this change is useful, since regmap is always initialized
below anyway.

That's not really useful with regmap_update_bits() which already does
the masking, no?

Couldn't this be:
if (mute)
val = 0;
else
val = PCM1789_MUTE_MASK;
ret = regmap_update_bits(priv->regmap, PCM1789_SOFT_MUTE,
PCM1789_MUTE_MASK, val);

Nit: the closing curly brace should be on a separate line.

Perhaps a "else" here ?

Thanks!
