[PATCH 01/13] ASoC: mediatek: mt8189: Return error for missing regmap

[phucduc.bui at gmail.com]

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

mt8189_afe_enable_top_cg() currently returns success when the AFE
regmap is unavailable.

Return -EINVAL so callers can handle the error.

Fixes: dc637ffeed6c ("ASoC: mediatek: mt8189: support audio clock control")
