I think better to display name, if there is nothing else to display, 
comparing to not display anything at all.
Command can be run on the driver object, .so, so user expects to see 
some output.

For above enetfec driver, it is virtual driver and doesn't support 
pci_ids, and it seems doesn't have parameters or kmod requirements.
So in this case it is OK to have only name.
