The las0, las1, and lcfg variables in struct rtdPrivate are all
ioremap'ed pci resources and should be void __iomem *
not void *.
This quiets a lot of sparse warings for the writel and readl 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 *
