Subject: [PATCH 112/182] pinctrl: samsung: use gpiochip data pointer
Date: Wed,  9 Dec 2015 14:33:12 +0100	[thread overview]
Message-ID: <1449667992-3104-1-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().
