in .remove function, better to set NUL after free, just like others.
in drivers/power/twl4030_charger.c, has already set NULL after free.
in drivers/input/keyboard/twl4030_keypad.c, has already set NUL after free.

additional info:
maybe this is not a bug, only for beautify code (can treat it as minor patch)
