cppcheck detected an unitialized variable:
Uninitialized.
[drivers/pinctrl/mediatek/pinctrl-mtk-common.c:897]: (error) Uninitialized variable: unmask
unmask should be initialized to zero to ensure unmasking only occurs if a previous mask occurred. The current situation is that the unmask variable could contain any random garbage causing random unexpected unmasking.
