From c2aea142af6179d757424a21110da3fc90127e02 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 23:44:39 +0100 Subject: ASoC: wm8996: 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().
