tile: array underflow in setup_maxnodemem()
My static checker correctly complains that we should have a lower bound on "node" to prevent an array underflow. Fixes: 867e359b97c9 ("arch/tile: core support for Tilera 32-bit chips.") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Chris Metcalf <cmetcalf@mellanox.com>
