Pop quiz time, eh? :)
I think it was probably due to
commit 44d1240d006c9cd0249263b5449c8e4752500f6a
Author: Marek Szyprowski <m.szyprow...@samsung.com>
Date: Mon Jun 13 11:11:26 2016 +0200
drm: add generic zpos property
If you want want to grade my answer all you have to do is revert that
on 4.8 and see what happens. Might be interesting to see if I'm right
actually since the link between the WARN and that commit isn't entirely
obvious.
