3.13.11.4 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Eliad Peller <[email protected]> commit c1fbb258846dfc425507a093922d2d001e54c3ea upstream. cfg80211 is notified about connection failures by __cfg80211_connect_result() call. However, this function currently does not free cfg80211 sme. This results in hanging connection attempts in some cases e.g. when mac80211 authentication attempt is denied, we have this function call: ieee80211_rx_mgmt_auth() -> cfg80211_rx_mlme_mgmt() -> cfg80211_process_auth() -> cfg80211_sme_rx_auth() -> __cfg80211_connect_result() but cfg80211_sme_free() is never get called.
