From 0788b6448067f51c53ef0514a82e3d89f91dfabd Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 09:58:28 +0100 Subject: [PATCH] gpio: max732x: 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().
