According to the comments in include/linux/init.h: "Pointers to __devexit functions must use __devexit_p(function_name), the wrapper will insert either the function_name or NULL, depending on the config options." We have __devexit annotation for wm8782_remove(), thus add __devexit_p at necessary place. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
