From 824a1bc045cef278aec15bef35d8d0b59ce77856 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Mon, 24 Sep 2012 15:36:24 +0900 Subject: [PATCH] extcon: unregister compat link on cleanup Since extcon registers this compat link at device registration (extcon_dev_register), we should probably remove them at deregistration/cleanup.
