Subject: [PATCH] m68k: coldfire: gpio: use new line value setter callbacks

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.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.

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. We're in the process of
converting all GPIO drivers to using the new API. This series converts
all m68k board-file level controllers.
