Exactly the same as the last time we discussed it: that you're abusing
plane properties to contain fundamental properties of the buffer you
want to scan out, i.e. that which naturally belongs in the framebuffer
object rather than a separate plane property. And doing it in a way
which is prone to failure when userspace is unaware of these
properties too.

That being said, I hadn't noticed that this had moved to being a
purely Intel-private property, rather than touching Android core at
all, so if you can get it past the Intel DRM maintainers, then fine. I
was primarily watching out for core DRM.

Cheers,
Daniel
