From 709d71a17c3383eca79ce9142b8d4ddc0f8028d0 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 10:34:28 +0100 Subject: [PATCH] gpio: mpc8xxx: use gpiochip data pointer MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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().
