Subject: [PATCH 07/12] ASoC: codecs: tlv320adc3xxx: 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.
