drivers/video/backlight/lms283gf05.c: use GPIOF_INIT flags when using devm_gpio_request_one()
GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below: GPIOF_DIR_OUT (0 << 0) GPIOF_DIR_IN (1 << 0) So, when !pdata->reset_inverted is 1, the gpio pin can be set as input, instead of output. To prevent this problem, GPIOF_INIT flag should be used when using devm_gpio_request_one().
