Subject: [PATCH 2/5] ASoC: mediatek: mt8188-mt6359: clean up a return in codec_init

From: Dan Carpenter <dan.carpenter@...aro.org>

This code triggers a Smatch static checker warning and does sort of
look like an error path.

sound/soc/mediatek/mt8188/mt8188-mt6359.c:597 mt8188_max98390_codec_init() warn: missing error code? 'ret'

However, returning 0 is intentional.  Make that explicit.
