In the DT case the DT code understands a bit more of what's going on with the firmware parsing which makes things better (the code in the two paths is not identical, unlike ACPI) but yes, that's another aspect of why I'm not thrilled with this - if it's not the hotplug and coldplug that should be sharing code then perhaps it's along the firmware interface axis that we need to be sharing things. > Which makes me think that it is not possible to have a single path for > both, or maybe its not worth it. Do I miss something obvious? I think at a very high level what I'm looking at here is that we're having to write too much boilerplate per firmware interface. Perhaps the hotplug vs coldplug path isn't it, it looked like it from your patch, but there must be something here we're spending too much time on.
