[PATCH 12/28] ASoC: codecs: ak4458: Remove set but never checked variable 'ret'

[Lee Jones]

Looks as though the result of snd_soc_update_bits() has never been checked.

Fixes the following W=1 kernel build warning(s):

 sound/soc/codecs/ak4458.c: In function ‘ak4458_set_dai_mute’:
 sound/soc/codecs/ak4458.c:408:16: warning: variable ‘ret’ set but not used 
[-Wunused-but-set-variable]
