From db1d127053c4c525086673e39691d274668a458d Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 23:31:28 +0100 Subject: [PATCH] ASoC: wm5100: 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().
