From c63b30b08971ad5894061841a2c7f012eea747c0 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:34:33 +0100 Subject: [PATCH] gpio: stp-xway: 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().
