mac80211: fix rx->key NULL pointer dereference in promiscuous mode
Since: commit 816c04fe7ef01dd9649f5ccfe796474db8708be5 Author: Christian Lamparter <chunkeey@googlemail.com> Date: Sat Apr 30 15:24:30 2011 +0200 mac80211: consolidate MIC failure report handling is possible to that we dereference rx->key == NULL when driver set RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in promiscuous mode. This happen with rt73usb and rt61pci at least. Before the commit we always check rx->key against NULL, so I assume fix should be done in mac80211 (also mic_fail path has similar check).
