Subject: [PATCH v2 2/3] drm/panel: himax-hx8394: switch to devm_gpiod_get_optional() for reset_gpio
Date: Mon, 1 Jul 2024 14:28:36 +0530 [thread overview]
Message-ID: <20240701085837.50855-3-manikandan.m@microchip.com> (raw)
In-Reply-To: <20240701085837.50855-1-manikandan.m@microchip.com>
Switch the driver to use devm_gpiod_get_optional() on reset_gpio to avoid
driver probe issues when reset line is not specified.
