With patches applied up to this one I end up with

  CC [M]  drivers/gpu/drm/rockchip/rockchip_drm_vop.o
../drivers/gpu/drm/rockchip/rockchip_drm_vop.c: In function ‘vop_crtc_enable’:
../drivers/gpu/drm/rockchip/rockchip_drm_vop.c:985:46: error: macro "VOP_INTR_SET" requires 4 arguments, but only 3 given
  VOP_INTR_SET(vop, line_flag_num[0], vact_end);
                                              ^
../drivers/gpu/drm/rockchip/rockchip_drm_vop.c:985:2: error: ‘VOP_INTR_SET’ undeclared (first use in this function)
  VOP_INTR_SET(vop, line_flag_num[0], vact_end);
  ^~~~~~~~~~~~
../drivers/gpu/drm/rockchip/rockchip_drm_vop.c:985:2: note: each undeclared identifier is reported only once for each function it appears in

In patch4 you replace this again, with 
-	VOP_INTR_SET(vop, line_flag_num[0], vact_end);
+	VOP_REG_SET(vop, intr, line_flag_num[0], vact_end);

but this intermediate breakage should not happen, to keep bisectability.
