Subject: pinctrl: armada-37xx: Fix direction_output() callback behavior

From: Gregory CLEMENT <[email protected]>

commit 6702abb3bf2394f250af0ee04070227bb5dda788 upstream.

The direction_output callback of the gpio_chip structure is supposed to set the output direction but also to set the value of the gpio. For the armada-37xx driver this callback acted as the gpio_set_direction callback for the pinctrl.

This patch fixes the behavior of the direction_output callback by also applying the value received as parameter.
