From 1880657a15842d2e617789f98a7a68f61c870592 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 6 Dec 2015 00:32:16 +0100 Subject: [PATCH] gpio: dln2: 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().
