gpio: include linux/bug.h in interface header
Today's linux-next kernel started showing build errors for the use of WARN_ON in linux/gpio/consumer.h: In file included from drivers/video/backlight/pwm_bl.c:13:0: include/linux/gpio/consumer.h: In function 'gpiod_put': include/linux/gpio/consumer.h:81:2: error: implicit declaration of function 'WARN_ON' [-Werror=implicit-function-declaration] It's not clear why this never happened before, but this patch fixes it by including the header that contains the defintion of this macro.
