From c7b6f457cb53bceece484f4c528d1c149995e6c7 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:12:45 +0100 Subject: gpio: rcar: 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().
