3.16.85-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
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 >=.
Fixes: 109bade9c625 ("scsi: sg: use standard lists for sg_requests")
