clang points out the usage of an incorrect enum type in the list of supported image formats: drivers/staging/media/atomisp/pci/atomisp_subdev.c:49:65: error: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Werror,-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV21, 12, 12, CSS_FRAME_FORMAT_NV21, 0, CSS_FRAME_FORMAT_NV21 }, drivers/staging/media/atomisp/pci/atomisp_subdev.c:49:39: error: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Werror,-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV21, 12, 12, CSS_FRAME_FORMAT_NV21, 0, CSS_FRAME_FORMAT_NV21 }, { V4L2_MBUS_FMT_CUSTOM_NV12, 12, 12, CSS_FRAME_FORMAT_NV12, 0, CSS_FRAME_FORMAT_NV12 }, { MEDIA_BUS_FMT_JPEG_1X8, 8, 8, CSS_FRAME_FORMAT_BINARY_8, 0, ATOMISP_INPUT_FORMAT_BINARY_8 }, Checking the git history, I found a commit that disabled one such case because it did not work. It seems likely that the incorrect enum was part of the original problem and that the others do not work either, or have never been tested. Disable all the ones that cause a warning.
