Subject: Re: [PATCH 2/3] PCI: of: create DT nodes for PCI devices if they do
 not exists

In subject:

  PCI: of: Create DT nodes ... if they do not exist

The subject could be read as saying that you're going to create DT
nodes before the PCI devices exist, but I think you mean that when we
enumerate a PCI devices, we're *always* going to create a DT node for
it, even if the DT didn't mention it.

Maybe something like:

  PCI: of: Create DT node for every PCI device

although I see Rob thinks this should be done on demand instead of
doing it for every device, which sounds sensible to me.
