Okay, in this case patch 2 can be omitted.

But for my understanding, platform_devices created in acpi_bus_attach()
that are not hot-removable don't take a reference to the host_bridge,
right (at least when the host-bridge is hot-removable)?

Otherwise this would be a leak again in case the host-bridge gets
removed.
