Date: Thu Oct 06 2016 - 04:57:42 EST


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

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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 55f1cf83d5cf885c75267269729805852039c834 upstream.

The pio_dev[] array has MAX_NR_PIO_DEVICES elements so the > should be
>=.
