The iobase variables in struct pci20xxx_subdev_private and ioaddr
variable in struct pci20xxx_private should be void __iomem * not
void *.
This quiets a lot of sparse warings for the writeb and readb calls
like:
warning: incorrect type in argument 1 (different address spaces)
expected void const volatile [noderef] <asn:2>*addr
got void *<noident>
warning: incorrect type in argument 2 (different address spaces)
expected void volatile [noderef] <asn:2>*addr
got void *
