staging: comedi: gsc_hpdi: plx9080_iobase and hpdi_iobase are void __iomem *
The plx9080_iobase and hpdi_iobase variables in struct hpdi_private
are ioremap'ed pci resource and should be void __iomem * not void *.
This quiets a lot of sparse warings for the writel and readl 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 *
