From f372d5f59cc4879eee3efe19e309f95c4078d748 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 6 Dec 2015 10:51:13 +0100 Subject: [PATCH] gpio: f7188: 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().
