When reconfiguring a plane position (as in moving the cursor), the frame buffer for the cursor isn't changing, so don't call the prepare or cleanup driver functions. This avoids making cursor position updates block on all pending rendering. v3: use drm_atomic_helper_framebuffer_changed in both prepare and cleanup phases instead of keeping state in the plane. cc: dri-devel@lists.freedesktop.org cc: David Airlie <airlied@linux.ie> cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: NKeith Packard <keithp@keithp.com> [danvet: Rebase onto 4.8] Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>
