But it is *not* standalone as I tried to explain above.

So you have to drop it again as the later patches depend on it and
cannot be merged (through a different tree) without it.

I thought you had all the acks you needed to take this through drm-misc,
but we can wait a bit more if necessary (and there's no rush to get the
first one in).
