Subject: mac80211: fix monitor interface suspend crash regression
From: Stanislaw Gruszka <[email protected]>
commit cd34f647a78e7f2296fcb72392b9e5c832793e65 upstream.
My commit:
commit 12e7f517029dad819c45eca9ca01fdb9ba57616b
Author: Stanislaw Gruszka <[email protected]>
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.
