Your original patch removed __init completely. Here you change it to
__devinit. That means we decide whether to discard the function based
on whether CONFIG_HOTPLUG is supported. But I think your point is not
about hotplug; it's merely that we should be able to scan a PCI bus
after init-time. We ought to be able to do a late PCI scan even if
hotplug is not supported.
Therefore, I'd be inclined to remove __init completely unless you have
another reason for preferring __devinit.
