Subject[patch 22/56] 8250_pci: add support for netmos 9835 IBM devices
2.6.27-stable review patch.  If anyone has any objections, please let us know.
------------------
From: Jiri Slaby <jirislaby@gmail.com>

commit 25cf9bc1fcb085daaeb82b09bab0fb3c40570887 upstream.

Most of netmos 9835 hardware is handled by parport-serial. IBM introduces
a device which doesn't have any parallel ports and have screwed subdevice
PCI id (not corresponding to port numbers).

Handle this device (9710:9835 1014:0299) properly.
