Subject[PATCH 1/1] parport: parport_serial, don't bind netmos ibm 0299
Date
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.
