right, we are dupping this for bus_find_device in:
./arch/powerpc/platforms/pseries/ibmebus.c
./drivers/gpu/drm/drm_mipi_dsi.c
./drivers/hwtracing/coresight/of_coresight.c
./drivers/of/of_mdio.c
./drivers/of/platform.c
./drivers/i2c/i2c-core-of.c
./drivers/nvmem/core.c

and for class_find_device in:
./drivers/spi/spi.c
./drivers/fpga/fpga-mgr.c
./drivers/fpga/fpga-region.c
./drivers/fpga/fpga-bridge.c
./drivers/regulator/core.c
./drivers/mux/core.c
./drivers/net/phy/mdio_bus.c

and for component_match_add in:
./drivers/iommu/mtk_iommu.c
  (and a lot of drm drivers)
