Subject: [PATCH 0/6] hid: use new GPIO setter callbacks

Commit 98ce1eb1fd87e ("gpiolib: introduce gpio_chip setters that return
values") added new line setter callbacks to struct gpio_chip. They allow
to indicate failures to callers. We're in the process of converting all
GPIO controllers to using them before removing the old ones. This series
converts all GPIO drivers under drivers/hid/.
