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.

Other than that:
