drivers/gpio/gpio-msm-v1.c: In function 'gpio_msm_v1_probe':
drivers/gpio/gpio-msm-v1.c:656:2:
error: implicit declaration of function 'IS_ERR'
[-Werror=implicit-function-declaration]
drivers/gpio/gpio-msm-v1.c:657:3:
error: implicit declaration of function 'PTR_ERR'
[-Werror=implicit-function-declaration]
