Hello, I see that I consistently get the warning below on v4.2-rc8. I
believe you already fixed this a long time ago by commit c0165304e10f
("drm/i915: Only enable cursor if it can be enabled."), which I assume is
a stable candidate for v4.2.y.
But wouldn't it look better if you managed to squeeze this into v4.2?
The warning will probably cause a few unnecessary worries and reports
from users...
Sample WARNING from v4.2-rc8, minus the irrelevant list of modules:
