Subject: ASoC: rt5677: use gpiochip data pointer
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=14900363454b8244b41f77f42013a22db20bb2e2;p=deliverable%2Flinux.git

ASoC: rt5677: 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().
