[PATCH v3 1/2] gpio: moxart: Avoid forward declaration

[PATCH v3 1/2] gpio: moxart: Avoid forward declaration

[Axel Lin]

Slightly adjust the code to avoid forward declaration as we need to call
moxart_gpio_set() in moxart_gpio_direction_output() to properly set the
output state.

[PATCH v3 2/2] gpio: moxart: Actually set output state in moxart_gpio_direction_output()

[Axel Lin]

moxart_gpio_direction_output() ignored the state passed into it. Fix it.

This patch is already upstream in Torvalds' tree, but thanks anyway!
