'smbus' code do not have 'bus_add_child' method.So the BUS_ADD_CHILD
call do not take effect.
Call device_add_child(parent,"my",-1); or define bus_add_child method.
And you will need to know grandparent device name to bind the device
collectly.(Or should we need a way to get device attribute such as
Mother board, Video Capture BitBang,Video Capture Cooked,VGA Card and etc.)
