From e65078f1f3490c753f8c223b088e8a482968b891 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 15:00:49 +0100 Subject: [PATCH] powerpc: sysdev: cpm1: 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().
