Hi all,
I am sorry for it and later reply.

But I am sure I have included the parport_serial in the
kernel for my consumers at the time they report their
PCI 9835 Multi-I/O Controller didn't work which cause
this "culprit" patch.

I don't have the card in hand right now, so I can't
dig into it. After stare into parport_serial.c, yes,
it seems like it will handle this pci serial card.

Maybe I forget or miss something, I hope.

Thanks.
