Subject: [PATCH v4 1/8] gpiolib: notify user-space when a driver requests its own desc
Date: Thu, 17 Oct 2024 10:14:09 +0200 [thread overview]
Message-ID: <20241017-gpio-notify-in-kernel-events-v4-1-64bc05f3be0c@linaro.org> (raw)
In-Reply-To: <20241017-gpio-notify-in-kernel-events-v4-0-64bc05f3be0c@linaro.org>
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().
