Subject: [PATCH 122/182] pinctrl: vt8500-wmt: use gpiochip data pointer
Date: Wed, 9 Dec 2015 14:34:32 +0100 [thread overview]
Message-ID: <1449668072-3579-1-git-send-email-linus.walleij@linaro.org> (raw)
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().
