From 0ca8c5c4af758b2a8d763b33508f99a3116c3c01 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:41:02 +0100 Subject: [PATCH] gpio: tb10x: 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().
