From: Colin Ian King <colin.k...@canonical.com>
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.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 4f692926f562 ("ASoC: codecs: lpass-rx-macro: add dapm widgets and route")
