    mac80211: station state transition error handling · 83d5cc01
    Johannes Berg authored
    In the future, when we start notifying drivers,
    state transitions could potentially fail. To make
    it easier to distinguish between programming bugs
    and driver failures:
     * rename sta_info_move_state() to
       sta_info_pre_move_state() which can only be
       called before the station is inserted (and
       check this with a new station flag).
     * rename sta_info_move_state_checked() to just
       plain sta_info_move_state(), as it will be
       the regular function that can fail for more
       than just one reason (bad transition or an
       error from the driver)
    
    This makes the programming model easier -- one of
    the functions can only be called before insertion
    and can't fail, the other can fail.
