From b7c17b1b97d3b5cbbcc0e902823b7ade5dbb4c4a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:48:49 +0100 Subject: [PATCH] gpio: tps65910: 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().
