Function assign_resources

src/device/device.c:298–320

* Assign the computed resources to the devices on the bus. * * Use the device specific set_resources() method to store the computed * resources to hardware. For bridge devices, the set_resources() method * has to recurse into every down stream buses. * * Mutual recursion: * assign_resources() -> device_operation::set_resources() * device_operation::set_resources() -> assign_resources() *

 * @param bus Pointer to the structure for this bus.
