Um, according to patchwork, you only posted it yesterday.  Does DRM
normally expect a review within 24 hours?

It seems a little odd to me to expect a drive-by contributor (ie me) to
rebase their patches on top of a patch series which wasn't even posted
at the time they contributed their original patch.  If it was already
in -next, that'd be a reasonable request.
