From 0b2c529a3b4d78d700c616e146411594a60cab18 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:29:48 +0100 Subject: [PATCH] gpio: sta2x11: 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().
