From 0ce242ad2ec17ddab1e3e3185b33c78f70df080a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 24 Jul 2019 10:38:28 +0200 Subject: pinctrl: qcom: Pass irqchip when adding gpiochip We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For chained irqchips this is a pretty straight-forward conversion.
