mac80211: safely free beacon in ieee80211_if_reinit
If ieee80211_if_reinit() is called from ieee80211_unregister_hw() then it is possible that the driver will still request a beacon (it is allowed to until ieee80211_unregister_hw() has returned.) This means we need to use an RCU-protected write to the beacon information even in this function. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
