In which case you should go for (tabs replaced by spaces to avoid e-mail

                if (!page_flip_needed(plane_state, old_plane_state, true,
                                      crtc->state->pflip_flags) ||
                    action == DM_COMMIT_ACTION_DPMS_ON || 
                    action == DM_COMMIT_ACTION_SET) {
