The uvc driver uses this function to fill in bus_info for VIDIOC_QUERYCAP, so use the same function when filling in the bus_info for the media device. The current implementation only fills in part of the info. E.g. if the full bus_info is usb-0000:01:00.0-1.4.2, then the media bus_info only has 1.4.2.
