From 57683ec203a642e8fc8befac94c8341d237f5d54 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 4 Dec 2015 15:26:35 +0100 Subject: [PATCH] gpio: amd8111: 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().
