[PATCH] parport: NetMos nm9855 fix

Browse source 
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://lists.infradead.org/pipermail/linux-parport/2005-February/000250.html
   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.
