    ath9k: handle RoC cancel correctly · d83520b7
    Janusz.Dziedzic@tieto.com authored
    In case we will get ROC cancel from mac80211 we
    should not call ieee80211_remain_on_channel_expired().
    
    In other case I hit such warning on MIPS and
    p2p negotiation failed (tested with use_chanctx=1).
