Subject: [PATCH 3.12 59/84] avr32: off by one in at32_init_pio()

From: Dan Carpenter <dan.carpenter@...cle.com>

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

===============

commit 55f1cf83d5cf885c75267269729805852039c834 upstream.

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