Jingoo Han 84f6942cde 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().
