 * Sometimes, the media controller &media_device needs to be shared by more

 * than one driver. This function adds support for that, by dynamically

 * allocating the &media_device and allowing it to be obtained from the

 * struct &device associated with the common device where all sub-device

 * components belong. So, for example, on an USB device with multiple

 * interfaces, each interface may be handled by a separate per-interface

 * drivers. While each interface have its own &device, they all share a

 * common &device associated with the hole USB device.
