Sorry for the delay here.  This fell between the cracks.

Kalle can you apply this directly to your tree? I'll assign it to you.
And, if possible, add the cc-stable tag so it gets picked up. :)

Longer reasoning: generally we detect the hardware in a more
programmatic way, by checking the type from registers (and not relying
entirely on the PCI IDs), but for some reason this type of device is
still using the legacy way of matching the exact PCI ID to a device
type.  Thus, this patch is needed, at least for now.

Thanks!
