Subject: [PATCH 05/14] gpio: sim: use value returning setters
Date: Tue, 11 Feb 2025 13:09:39 +0100	[thread overview]
Message-ID: <20250211-gpio-set-retval-v1-5-52d3d613d7d3@linaro.org> (raw)
In-Reply-To: <20250211-gpio-set-retval-v1-0-52d3d613d7d3@linaro.org>

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

struct gpio_chip now has additional variants of the set(_multiple)
driver callbacks that return an integer to indicate success or failure.
Convert the driver to using them.
