[PATCH v3 1/6] gpiolib: notify user-space when a driver requests its own desc

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

We notify user-space about lines being requested from user-space or by
drivers calling gpiod_get() but not when drivers request their own lines
so add the missing call to gpiod_line_state_notify().
