Oh, another iteration of a driver-private zpos property. This _really_
should be generic, with some consistent cross-driver semantics. Marek from
samsung has started with a patch series for that.

Can you please work together with him, and rebase the sti zpos support on
top of his work? And hold of this patch for now meanwhile?

Also adding Marek.

Thanks, Daniel
