    kernel-labs: input: re-show the link structures
    
    This change has been accidentally dropped by:
    a97ebe43 ("labs, lab-data: update for embedded-linux new generation")
    and I expect it was done by mistake because I really think the figure
    helps attendees.

 Make sure you add this code before registering the input device. You
 don't want to enable a device with incomplete information or when it is
 not completely initialized yet (there could be race conditions).
