[PATCH 10/10] ASoC: mediatek: mt8196: propagate TDM clock errors

[phucduc.bui at gmail.com]

From: bui duc phuc <phucduc.bui at gmail.com>

Propagate errors from BCK and MCK clock operations in the DAPM event
callbacks instead of always returning success.

Fixes: ede4d841111a ("ASoC: mediatek: mt8196: support TDM in platform driver")
