From 014c1b3de3bec90df119e718d3f9f131747609bf Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 09:33:30 +0100 Subject: [PATCH] pinctrl: u300: 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().
