    drm/panel: simple: Assign data from panel_dpi_probe() correctly
    
    [ Upstream commit 6df4432a5eca101b5fd80fbee41d309f3d67928d ]
    
    In the function panel_simple_probe() the pointer panel->desc is
    assigned to the passed pointer desc. If function panel_dpi_probe()
    is called panel->desc will be updated, but further on only desc
    will be evaluated. So update the desc pointer to be able to use
    the data from the function panel_dpi_probe().
