A single USB function can be implemented using a group of interfaces and this is for example commonly used for Communication Class devices. Add support for multi-interface functions to USB serial core and export an interface that allows drivers to claim a second sibling interface. The interface could easily be extended to allow claiming further interfaces if ever needed. When a driver claims a sibling interface in probe(), core allocates resources for any bulk in, bulk out, interrupt in and interrupt out endpoints found also on the sibling interface. Disconnect is implemented so that unbinding either interface will release the other interface while disconnect() is called precisely once. Similarly, suspend() is called when the first sibling interface is suspended and resume() is called when the last sibling interface is resumed by USB core.
