Include the header to pickup the exported symbol prototype.

83e72dd97a apple_bl: Add register/unregister functions 
Add functions to allow other modules to enable or disable apple_bl. This
will be used by the gmux driver to disable apple_bl when the gmux is
present, as it is a better and more reliable option for brightness
control.
