Subject: [PATCH 07/12] gpio: tpic2810: use new GPIO line value setter callbacks
Date: Wed, 02 Jul 2025 11:14:08 +0200 [thread overview]
Message-ID: <20250702-gpiochip-set-rv-gpio-round3-v1-7-0d23be74f71d@linaro.org> (raw)
In-Reply-To: <20250702-gpiochip-set-rv-gpio-round3-v1-0-0d23be74f71d@linaro.org>
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.
