Subject: [PATCH 15/19] gpio: xtensa: use new GPIO line value setter callbacks
Date: Wed, 09 Jul 2025 08:41:52 +0200 [thread overview]
Message-ID: <20250709-gpiochip-set-rv-gpio-remaining-v1-15-b8950f69618d@linaro.org> (raw)
In-Reply-To: <20250709-gpiochip-set-rv-gpio-remaining-v1-0-b8950f69618d@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.
