leds: leds-lt3593: set devm_gpio_request_one() flags param correctly
The devm_gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | state GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below: GPIOF_DIR_OUT (0 << 0) GPIOF_DIR_IN (1 << 0) So, when 'state' is 1, the gpio pin can be set as input, instead of output. To prevent this problem, GPIOF_OUT_INIT flags should be used when using devm_gpio_request_one(). Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
