Subject: [PATCH 156/182] input: adp5589-keys: use gpiochip data pointer
Date: Wed,  9 Dec 2015 14:45:10 +0100	[thread overview]
Message-ID: <1449668710-5785-1-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().

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