| |
3.16.40-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 0e1614ac84f1719d87bed577963bb8140d0c9ce8 upstream.
Make sure to drop the reference to the parent device taken by class_find_device() after "unexporting" any children when deregistering a PWM chip.
