[ 042/102] mac80211: fix monitor interface suspend crash regression
3.10-stable review patch. If anyone has any objections, please let me know. -- From: Stanislaw Gruszka commit cd34f647a78e7f2296fcb72392b9e5c832793e65 upstream. My commit: commit 12e7f517029dad819c45eca9ca01fdb9ba57616b Author: Stanislaw Gruszka Date: Thu Feb 28 10:55:26 2013 +0100 mac80211: cleanup generic suspend/resume procedures removed check for deleting MONITOR and AP_VLAN when suspend. That can cause a crash (i.e. in iwlagn_mac_remove_interface()) since we remove interface in the driver that we did not add before.
