From 95bf0951e415cf71654184fd6e8c711782b1f22a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 13:48:02 +0100 Subject: avr32: gpio: 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().
