Subject: [PATCH v2 11/15] gpio: max77650: use value returning setters
Date: Thu, 20 Feb 2025 10:57:08 +0100 [thread overview]
Message-ID: <20250220-gpio-set-retval-v2-11-bc4cfd38dae3@linaro.org> (raw)
In-Reply-To: <20250220-gpio-set-retval-v2-0-bc4cfd38dae3@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.
