From b4e97a61255cde7e5b2f2484140547ba37c7292c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 4 Dec 2015 15:36:14 +0100 Subject: gpio: ath79: 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().
