PATCH 1/1 staging: comedi: icp_multi: io_addr is a void __iomem *

The io_addr variable in struct dt3k_private is an ioremap'ed pci resource and should be void __iomem * not a void *.

This quiets a lot of sparse warings for the writew and readw 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 *
