4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> commit bd46fc406b30d1db1aff8dabaff8d18bb423fdcf upstream. If "val" is SG_MAX_QUEUE then we are one element beyond the end of the "rinfo" array so the > should be >=.
