  drm/rockchip: Delete an unnecessary check before drm_gem_object_unreference_unlocked()
  drm/rockchip: fix a couple off by one bugs
  drm/rockchip: vop: correct rk3036 register define
  drm/rockchip: vop: correct the source size of uv scale factor setting
  drm/rockchip: vop: add uv_vir register field for RK3036 VOP
  drm/rockchip: fix "should it be static?" warnings
