Three little fixes:

Browse source 
* revert a recent wext patch, which Ben Hutchings noticed was
    wrong, and it turns out not to be necessary for any driver
 
  * fix an infinite loop that can occur under certain conditions
    in mac80211's TDLS code (depending on regulatory information)
 
  * add a cfg80211_get_station() static inline when cfg80211 isn't
    built, to allow other modules to not have to depend on it for it
