Absolutely. It's only meant to add the call chains for all the resource 
additions, so that we could see how that buggy 'c2' resource gets added as 
a parent to 'c3' (when it should be the other way around).

Sure. Or increase CONFIG_LOG_BUF_SHIFT to 22 or somethng insane like that 
(so that it logs up to 4MB of messages).

But yeah, if you just make it smarter, and only do that WARN() thing for 
resources that match "PCI Bus" at the beginning of the name, that should 
be plenty good enough.
