Subject: [PATCH 02/12] ASoC: ti: davinci-mcasp:: use new GPIO 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.
