[PATCH 0/2] PCI: Add and use pcim_iomap_region()

[Heiner Kallweit <hkallweit1@gmail.com>]

Several drivers use the following sequence for a single BAR:
rc = pcim_iomap_regions(pdev, BIT(bar), name);
if (rc)
	error;
addr = pcim_iomap_table(pdev)[bar];

Let's create a simpler (from implementation and usage perspective)
pcim_iomap_region() for this use case.

Note: The check for !pci_resource_len() is included in
pcim_iomap(), so we don't have to duplicate it.

Make r8169 the first user of the new function.

I'd prefer to handle this via the PCI tree.
