From: Linus Walleij Date: Wed, 9 Dec 2015 13:46:55 +0000 (-0200) Subject: [media] : cxd2830r: use gpiochip data pointer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27524ff8cd6c28ea3735f80f0374e0fc5494768f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [media] : cxd2830r: 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().
