Subject: [PATCH v2 02/11] gpiolib: add support for scope-based management to gpio_device
Date: Tue, 12 Sep 2023 12:07:18 +0200 [thread overview]
Message-ID: <20230912100727.23197-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20230912100727.23197-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
As the few users that need to get the reference to the GPIO device often
release it right after inspecting its properties, let's add support for
the automatic reference release to struct gpio_device.
