From f42b6f5800b6d06442c193d4beb423b0186e7b6a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 8 Dec 2015 23:41:55 +0100 Subject: [PATCH] ASoC: wm8962: 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().
