   For the patch, I would suggest to only skip call of `fb->vtable->updatearea` 
if it is set to NULL, not to go to panic. Because `CONFIG_FB_UPDATE` can be set 
to support combination of displays where one needs it and other has mapped real 
device side frame-buffer which is scanned to the screen periodically by 
hardware. `FBIO_UPDATE` does solve such situation by return of `-ENOTTY` but it 
can be simply ignored and common code can be used for displays with and without 
need of explicit updates.
