The second patch is applied now, but this part is still missing in
v4.17-rc1, causing the CSI subdev probe to fail:

  imx-ipuv3-csi: probe of imx-ipuv3-csi.0 failed with error -1369528304
  imx-ipuv3-csi: probe of imx-ipuv3-csi.1 failed with error -1369528304
  imx-ipuv3-csi: probe of imx-ipuv3-csi.5 failed with error -1369528304
  imx-ipuv3-csi: probe of imx-ipuv3-csi.6 failed with error -1369528304
