Subject: gpio: tps6586x: use new GPIO line value setter callbacks
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e3ec7ad5ab139ad9e0ed8931ba562f95698c3b2f;p=thirdparty%2Flinux.git

gpio: tps6586x: use new GPIO line value setter callbacks

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