    mac80211: delete the assoc/auth timer upon suspend · c1e140bf
    Emmanuel Grumbach authored
    While suspending, we destroy the authentication /
    association that might be taking place. While doing so, we
    forgot to delete the timer which can be firing after
    local->suspended is already set, producing the warning below.
    
    Fix that by deleting the timer.
