No, I think it's not quite that bad. I think the rule is still just that .probe() functions and anything called from them must not be __init. They used to be __devinit, which would cause problems with deferred probing on !HOTPLUG systems but that's gone in 3.9. Thierry's patch is just necessary because pci_common_init used to be called only from actual __init functions, and not it gets called from a .probe() function for the first time.
