When CONFIG_GPIOLIB is not set, we get a couple of build errors during test building: drivers/input/misc/msm-vibrator.c: In function 'msm_vibrator_start': drivers/input/misc/msm-vibrator.c:79:3: error: implicit declaration of function 'gpiod_set_value_cansleep'; did you mean 'gpio_set_value_cansleep'?
