Subject: [PATCH 01/12] gpio: tegra186: don't call the set() callback directly
Date: Wed, 02 Jul 2025 11:14:02 +0200 [thread overview]
Message-ID: <20250702-gpiochip-set-rv-gpio-round3-v1-1-0d23be74f71d@linaro.org> (raw)
In-Reply-To: <20250702-gpiochip-set-rv-gpio-round3-v1-0-0d23be74f71d@linaro.org>
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
Drivers should not dereference GPIO chip callbacks directly. Move the
module's set() function higher to make it available to the
direction_output() callback and call it instead.
