Note: the pza/imx-drm/next HEAD 82581fcf070b68a91fb3a3ade08d9a76380a4789 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):

   mips-linux-ld: drivers/gpu/drm/imx/dw_hdmi-imx.o: in function `dw_hdmi_imx_probe':
>> dw_hdmi-imx.c:(.text+0x2c0): undefined reference to `of_drm_find_bridge'
