Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
This allows to drop the explicit setting of direction.
Furthermore this is one caller less that stops us making the 3rd
argument mandatory.
