Andrew, one more netmos 9835 patch, I though parport_serial binds only SERIAL_OTHER pci subclass devices which was apparently wrong assumption. Please apply.

Since netmos 9835 with subids 0x1014(IBM):0x0299 is now bound with serial/8250_pci, because it has no parallel ports and subdevice id isn't in the expected form, return -ENODEV from probe function.
This is performed in netmos preinit_hook.
