+- Make ->funcs and ->helper_private vtables optional. There's a bunch of empty
+  function tables in drivers, but before we can remove them we need to make sure
+  that all the users in helpers and drivers do correctly check for a NULL

+- Cleanup up the various ->destroy callbacks. A lot of them just wrapt the
+  drm_*_cleanup implementations and can be removed. Some tack a kfree() at the
+  end, for which we could add drm_*_cleanup_kfree(). And then there's the (for
+  historical reasons) misnamed drm_primary_helper_destroy() function.
