PCI: ia64: use generic pci_enable_resources()
Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - does not check for a NULL dev pointer - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
