ast currently ioremaps two PCI BARs using pcim_iomap(). It does not perform a request on the regions, however, which would make the driver a bit more robust. PCI now offers pcim_iomap_region(), a managed function which both requests and ioremaps a BAR. Replace pcim_iomap() with pcim_iomap_region().
