From d94780444bf3da8fc35e281aec6bbffa54a4a01a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 16:35:27 +0100 Subject: [PATCH] input: ad7879: use gpiochip data pointer This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of().
