[Greg Kroah-Hartman]

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpen...@oracle.com>

[ Upstream commit c54c1c5ee8e73b7cb752834e52e2129b1dab00bd ]

The > should be >= or we could read one element beyond the end of the
port_maps[] array.
