3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Huewe <peterhuewe@gmx.de>

commit 824a1bc045cef278aec15bef35d8d0b59ce77856 upstream.

Since extcon registers this compat link at device registration
(extcon_dev_register), we should probably remove them at deregistration/cleanup.
