commit 86ecb7d6853c77711c14cb6600179196f179ee2d upstream.
drivers/pinctrl/mediatek/pinctrl-mtk-common-v2.c: In function mtk_hw_pin_field_lookup:
drivers/pinctrl/mediatek/pinctrl-mtk-common-v2.c:70:39: warning:
variable e set but not used [-Wunused-but-set-variable]
Since commit 3de7deefce69 ("pinctrl: mediatek: Check gpio pin
number and use binary search in mtk_hw_pin_field_lookup()"),
it is not used any more, so remove it, also remove redundant
assignment to variable c, it will be assigned a new value later
before used.
