PCI: Index IOV resources in the conventional style
Most of PCI uses "res = &dev->resource[i]", not "res = dev->resource + i". Use that style in iov.c also. No functional change. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Wei Yang <weiyang@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
