It looks like you just added this array in the previous patch, remove it
here, and then you add it back (with only a single element) in the next
patch. I suspect this is just an artifact of your rebasing and
respinning the patch series, but if you agree my suggestion on the
previous patch to drop the array completely, please make sure that it's
dropped throughout the series to keep the review simple. :-)

I think it's generally a bit easier to review if you just add the
functions with their bodies when you actually have the implementation.
I can see where you call these functions in the code below, but without
the bodies present, it makes it a little harder for reviewers to see
whether those are correct. Since this patch doesn't do anything by
itself, I'd suggest dropping it and just squashing the changes here into
your future patches.
Also, it looks like the plane function remains a noop throughout your
patch series, so I'd just leave it out completely until you start
introducing the plane properties that will use it.
