[PATCH 4/4] ASoC: mediatek: mt6359: fix UNINIT problem

From: Trevor Wu
Date: Mon Mar 06 2023 - 23:09:54 EST


Coverity shows decaring variable reg without initializer. When
regmap_read returns an error, reg keeps the value left from earlier
computation. To prevent from the unexpected result in the case, assign
0 to reg.
