From: Jiri Slaby Date: Thu, 15 Jan 2009 13:30:34 +0000 (+0000) Subject: 8250_pci: add support for netmos 9835 IBM devices X-Git-Tag: MMI-PSA29.97-13-9~29853 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25cf9bc1fcb085daaeb82b09bab0fb3c40570887;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git 8250_pci: add support for netmos 9835 IBM devices 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.
