Hi,

I have a HFC IOB1E1 PCI card.
The linux kernel is not very happy with the card, I get

        Unknown HFC multiport controller (vendor:1397 device:30b1
        subvendor:1397 subdevice:b543)
        Please contact the driver maintainer for support.

The same error is mentioned in [1] but with different subdevice id, 
which I believe does not matter.
I am not sure why vendor ID 1397 (PCI_VENDOR_ID_CCD) and device ID 30b1 
(PCI_DEVICE_ID_CCD_HFCE1) are not valid. Consulting [2] I was under the 
impression that this is the expectation of the driver.
[1] does not provide an answer as far as I can see.
Would anybody know what the problem is here?
The best guess I have at the moment is that m == NULL, implying that 
ent->driver_data == NULL. Would there be a valid reason for that I do 
not know?
I would be thankful for any suggestions.

-Alex
