In this case a pointer to "struct vnt_private" is given to macros @MACvRegBitsOn()
and @MACvRegBitsOff().  These in turn eventually call @ioread8(), which take a
"void __iomem *" as parameter.  The first field of "struct vnt_private" is a
pointer to a "struct pci_dev", whose first field is a "struct list_head".

Correcting the problem by following the trend set fort in every other calls to
the macros by passing "->PortOffset", declared as "void __iomem *".
