[PATCH 3.10 071/319] avr32: off by one in at32_init_pio()

From: Willy Tarreau
Date: Sun Feb 05 2017 - 14:23:21 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 55f1cf83d5cf885c75267269729805852039c834 upstream.

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