3.16.52-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 637f23abca87d26e091e0d6647ec878d97d2c6cd upstream.
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.")
