[PATCH] staging: comedi: dt3000: io_addr is a void __iomem *

[H Hartley Sweeten]

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)
 Âexpected void const volatile [noderef] <asn:2>*addr
 Âgot void *<noident>

warning: incorrect type in argument 2 (different address spaces)
 Âexpected void volatile [noderef] <asn:2>*addr
 Âgot void *
