The ivi-shell keeps track of its surfaces by adding them to the ivi_surface_list to be able to remove them on shutdown. It also creates an ivi_layout_surface for a desktop surface, but does not keep track of these surfaces. During compositor shutdown, libweston prints the following message: BUG: finalizing a layer with views still on it. Fix it by adding the created ivi_layout_surface to the ivi_surface_list to remove the surfaces from the layer during shutdown. Furthermore, remove the ivi_layout_surface from the desktop surface and free it when the desktop surface is destroyed. Signed-off-by: Michael Tretter <m.tretter@pengutronix.de>
