From 78132252cc4c6cecec25491a7bcfb6567bf29147 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 7 Dec 2015 14:16:19 +0100 Subject: [PATCH] gpio: rdc321x: 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().
