Subject: parport_serial: fix array overflow
From: Takashi Iwai <tiwai@xxxxxxx>
The netmos_9xx5_combo type assumes that PCI SSID provides always the
correct value for the number of parallel and serial ports, but there are
indeed broken devices with wrong numbers, which may result in Oops.
This patch simply adds the check of the array range.
