Here you go:

static int smc_request_attrib(struct platform_device *pdev,
         struct net_device *ndev)
{
 struct resource * res = platform_get_resource_byname(pdev, 0x00000200,
"smc91x-attrib");

 if (!res)
  return 0;

 if (!__request_region(&iomem_resource, (res->start), (((64*1024) <<
(lp->io_shift))), ("smc91x")))
  return -16;

 return 0;
}
