[PATCH v4 2/2] ASoC: codecs:lpass-wsa-macro: Fix logic of enabling vi channels
Posted by srinivas.kandagatla@linaro.org 1 week ago 
From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Existing code only configures one of WSA_MACRO_TX0 or WSA_MACRO_TX1
paths eventhough we enable both of them. Fix this bug by adding proper
checks and rearranging some of the common code to able to allow setting
both TX0 and TX1 paths

Without this patch only one channel gets enabled in VI path instead of 2
channels. End result would be 1 channel recording instead of 2.

Fixes: 2c4066e5d428 ("ASoC: codecs: lpass-wsa-macro: add dapm widgets and route")
