  sound/soc/rockchip/rockchip_i2s.c:569:34: warning: ‘rockchip_i2s_match’ defined but not used [-Wunused-const-variable=]
  sound/soc/rockchip/rockchip_pdm.c:463:34: warning: ‘rockchip_pdm_match’ defined but not used [-Wunused-const-variable=]
  sound/soc/rockchip/rockchip_spdif.c:44:34: warning: ‘rk_spdif_match’ defined but not used [-Wunused-const-variable=]
