Sorry, this is getting into bike-shed territory.
I'm a lot happier with the code now, so may as well fix up a few
style issues before it goes in.

Strictly speaking, you don't need those curly braces. If you want
readability, how about moving the comment up?
/* Only setup prefetch resources */
if (type & IORESOURCE_PREFETCH)
type = IORESOURCE_PREFETCH;

Useless comment.

Can clean this up a bit too with short-circuit logic.
if ((rel_type == whole_subtree) || is_leaf_bridge)
pci_bridge_release_resources(bus, type);
If you clean those up, you can add my:
