[PATCH] pinctrl: ma35: use new GPIO line value setter callbacks

[PATCH] pinctrl: ma35: use new GPIO line value setter callbacks

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

I realized one of the pinctrl drivers was missed during the conversion.
