backlight: pwm_bl: Simplify usage of devm_gpiod_get_optional
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions), the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify the usage of devm_gpiod_get_optional accordingly. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
