It turned out that there was also a change queued for drm-misc that was renaming (and changing the prototype of) drm_plane_helper_check_state into drm_atomic_helper_check_plane_state.

We don't rebase in drm-misc, so please send an additional patch. Thanks! Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
