From 8d5f095fc5f7e36f40a80e87317828be249ee454 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 30 Mar 2016 10:48:03 +0200 Subject: [PATCH] mfd: htc-egpio: 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().
