Subject: [PATCH] gpio: xlp: Pass irqchip when adding gpiochip
Date: Fri, 9 Aug 2019 15:51:19 +0200 [thread overview]
Message-ID: <20190809135119.6946-1-linus.walleij@linaro.org> (raw)
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion.
