Thanks, this looks solid - unfortunately it fails to apply on top of
`drm-rust-next` (not your fault, the patchset was sent before -rc1 got
tagged). Patch 1 has a trivial conflict due to the removal of the
`Display` implementation, but patch 8 does not even give me the option
to resolve anything. Could you rebase on top of `drm-rust-next` and send
a v3? I would like to experiment a bit with patch 8 but cannot do it
unfortunately.
