[PATCH] bcma: use new GPIO line value setter callbacks
Posted by Bartosz Golaszewski 8 months, 1 week ago
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.
