3.16.7-ckt5 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Antonio Quartulli <[email protected]> commit 0d1644919578db525b9a7b6c8197ce02adbfce26 upstream. Gateway having bandwidth_down equal to zero are not accepted at all and so never added to the Gateway list. For this reason checking the bandwidth_down member in batadv_gw_out_of_range() is useless. This is probably a copy/paste error and this check was supposed to be "!gw_node" only. Moreover, the way the check is written now may also lead to a NULL dereference. Fix this by rewriting the if-condition properly.
