+[PATCH] mac80211: hoist sta->lock from reorder release timer
+
+The patch "mac80211: AMPDU rx reorder timeout timer" clashes
+with "mac80211: use netif_receive_skb in ieee80211_rx callpath"
+
+The timer itself is part of the station's private struct and
+it gets killed whenever the station is removed. Therefore
+the extra sta->lock protection (that can interferes with the
+tx path) is not necessary.
