      I got the following WARN on a simple unbind/bind cycle:

      This gets fixed by clearing the control device pointer on async_unbind.

      [media] v4l: vsp1: Fix wrong entities links creation · 5017e1b1
      Javier Martinez Canillas authored
      The Media Control framework now requires entities to be registered with
      the media device before creating links so commit c7621b30 ("[media]
      v4l: vsp1: separate links creation from entities init") separated link
      creation from entities init.
      
      But unfortunately that patch introduced a regression since wrong links
      were created causing a boot failure on Renesas boards.
      
      This patch fixes the boot issue and also the media graph was compared
      by Geert Uytterhoeven to make sure that the driver changes required by
      the Media Control framework next generation did not affect the graph.
