This is touching drivers/edac/ and I guess I'm fine with it,

... one question though: how are people using those pci_bus* functions supposed to know that pci_bus_assign_resources needs to go before pci_bus_add_device? The comment in pci_bus_add_device() mentions something about it but wouldn't it be possible to call pci_bus_assign_resources() in pci_bus_add_device() when resources are not assigned?
Sorry if my question is completely dumb - I have no presumption of knowing pci and haven't looked either. Just asking with my user hat on.
Thanks.
