I'm curious what the plan is for landing this series. I could land the
first two in drm-misc if you want, but I'm a lowly committer and so I
couldn't make an immutable branch for you nor can I officially Ack the
changes to land in your branch. That means you'd be blocked for an
extra version. Do you already have a plan? If not, then maybe we need
to get in touch with one of the maintainers [1] of drm-misc? That's
documented [2] to be in their set of responsibilities.
