Looks like this broke omapdrm in linux-next:

drivers/gpu/drm/omapdrm/omap_crtc.c:470:2: error: initialization from
incompatible pointer type [-Werror]
drivers/gpu/drm/omapdrm/omap_crtc.c:470:2: error: (near initialization
for ‘omap_crtc_helper_funcs.atomic_begin’) [-Werror]
drivers/gpu/drm/omapdrm/omap_crtc.c:471:2: error: initialization from
incompatible pointer type [-Werror]
drivers/gpu/drm/omapdrm/omap_crtc.c:471:2: error: (near initialization
for ‘omap_crtc_helper_funcs.atomic_flush’) [-Werror]
