Subject[PATCH 01/16] ASoC: codecs: rx-macro: fix accessing compander for aux
Date
AUX interpolator does not have compander, so check before accessing
compander data for this.

Without this checkan array of out bounds access will be made in
comp_enabled[] array.

Fixes: 4f692926f562 ("ASoC: codecs: lpass-rx-macro: add dapm widgets and route")
