Ok, this is apparently just a leak for what appears to be a not
particularly interesting error case, but the warning is new to 4.20
(*) so it would be nice to have somebody look at it.
That commit is supposed to fix a leak, but there's apparently
something still there.
Daniel, Peter, Gerd?
(*) the *problem* is probably not new, it's just now exposed by the
switch to drm_mode_config_cleanup().
