Subject: [PATCH v5 1/8] gpiolib: notify user-space when a driver requests
its own desc
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.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().
