I do not think so. The previous patch passes the parent to the 
pci_create_root_bus(), indeed, so pci_create_root_bus() set companion 
device before calling pcibios_root_bridge_prepare() (for both cases x86 
and ia64). In turn, pcibios_root_bridge_prepare() will do nothing, since 
bridge->dev.parent != NULL. After all, pcibios_root_bridge_prepare() is 
dead code.
