Subject: [PATCH v12 3/7] gpiolib: of: make fwnode take precedence in struct gpio_chip
Date: Fri,  3 Dec 2021 14:29:59 +0100	[thread overview]
Message-ID: <20211203133003.31786-4-brgl@bgdev.pl> (raw)
In-Reply-To: <20211203133003.31786-1-brgl@bgdev.pl>

If the driver sets the fwnode in struct gpio_chip, let it take
precedence over the of_node.
