Seems this is against a rather old version of drm/i915. Can you pls
regenerate against linux-next or the drm-tip branch from
https://cgit.freedesktop.org/drm-tip
But in general, for large-scale refactoring like this, the recommendation
is to base them on linux-next, since that will have all pending patches
applied for every part of the kernel.
