Subject: [PATCH 165/182] mfd: sm501: use gpiochip data pointer
Date: Wed, 9 Dec 2015 14:47:53 +0100 [thread overview]
Message-ID: <1449668873-6354-1-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().

Lee please ACK this so I can take it through the GPIO tree.
