Subject: [PATCH 2/3] gpiolib: make gpiochip_get_desc() public

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

It makes sense for a GPIO driver to want to get its own descriptor
without requesting it. After all, the driver knows that it'll still be
valid. Let's move this helper to linux/gpio/driver.h.
