[PATCH] parport: NetMos nm9855 fix
kernel 2.6.12-rc2 adopted some code by Bjorn Helgaas supporting NetMos combo
controller cards. this implementation doesn't work for nm9855 based cards!
there are two reasons:
a) the module 'parport_pc' doesn't want to give the resonsibility for
the netmos_9855 to 'parport_serial' and can not handle the serial lines
-- trivial to fix...

http://lkml.org/lkml/2005/3/24/199 b) the support for the nm9855 in
'parport_serial' still doesn't work because of wrong assumptions about
the relevant BARs port address layout for this chip:
0000:00:09.0 Communication controller:
NetMos Technology PCI 9855
Multi-I/O Controller (rev 01)
(= 9710:9855)
Subsystem: LSI Logic / Symbios Logic 1P4S (= 1000:0014)
Flags: medium devsel, IRQ 177
I/O ports at a800 [size=8] (= parport)
I/O ports at a400 [size=8]
I/O ports at a000 [size=8] (= serial)
I/O ports at 9800 [size=8] (= serial)
I/O ports at 9400 [size=8] (= serial)
I/O ports at 9000 [size=16] (= serial)
the following patch will fix the problem.
