Subject: [PATCH v13 3/7] gpiolib: of: make fwnode take precedence in struct gpio_chip
Date: Tue,  7 Dec 2021 10:34:08 +0100	[thread overview]
Message-ID: <20211207093412.27833-4-brgl@bgdev.pl> (raw)
In-Reply-To: <20211207093412.27833-1-brgl@bgdev.pl>

If the driver sets the fwnode in struct gpio_chip, let it take
precedence over the of_node. This only affects OF-based systems,
ACPI needs to be converted separately.
