ASoC: mediatek: mt8188: avoid uninitialized variable use
The 'msk' variable has no initialization:
sound/soc/mediatek/mt8188/mt8188-dai-dmic.c:311:4: error: variable 'msk' is uninitialized when used here [-Werror,-Wuninitialized]
311 | msk |= PWR2_TOP_CON1_DMIC_FIFO_SOFT_RST_EN(i);
| ^~~
Set it to zero before the loop.
