From: Linus Walleij Date: Tue, 8 Dec 2015 22:48:29 +0000 (+0100) Subject: ASoC: ac97: use gpiochip data pointer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7cb5120c4e0de10c3e069f5318417da0326fb45;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ASoC: ac97: 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().
