2021-03-10ASoC: codecs: lpass-rx-macro: remove redundant initialization of variable ↵Colin Ian King
hph_pwr_mode The variable hph_pwr_mode is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

2021-03-10ASoC: codecs: lpass-rx-macro: Fix uninitialized variable ec_txColin Ian King
There is potential read of the uninitialized variable ec_tx if the call to snd_soc_component_read fails or returns an unrecognized w->name. To avoid this corner case, initialize ec_tx to -1 so that it is caught later when ec_tx is bounds checked.
