3.2.70-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jo...@kernel.org>
commit 01cca93a9491ed95992523ff7e79dd9bfcdea8e0 upstream.
Unregister gpiochip device (used to export information through sysfs)
before removing it internally. This way removal will reverse addition.
