From 2a6643437083c4dc28169a706099cd22769be1f5 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 16:42:58 +0100 Subject: [PATCH] leds: tca6507: 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().
