What was wrong with it?
Martin, does this change affect the hardware upon which you tested 44e58a6a0bd604f46be9d808408a1cd880cc9b19, "parport: NetMos nm9855 fix"?
Thanks.

What was wrong with it?
Hi,
on loading only one serial port was present and it wasn't working. After looking in the data sheet I realized that the base address was wrong. For further reference here is lspci and relevant dmesg output:
02:00.0 Communication controller: NetMos Technology PCI 9855 Multi-I/O Controller (rev 01) (prog-if 02)
