Ah excellent, that makes the warnings a lot more readable. I am still not sure how to reconcile the differences, it might be easier to just change the types in the struct to int. ../drivers/staging/media/atomisp/pci/atomisp_subdev.c:49:68: warning: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV21, 12, 12, IA_CSS_FRAME_FORMAT_NV21, 0, IA_CSS_FRAME_FORMAT_NV21 }, ~ ^~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/staging/media/atomisp/pci/atomisp_subdev.c:49:39: warning: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV21, 12, 12, IA_CSS_FRAME_FORMAT_NV21, 0, IA_CSS_FRAME_FORMAT_NV21 }, ~ ^~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/staging/media/atomisp/pci/atomisp_subdev.c:48:68: warning: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV12, 12, 12, IA_CSS_FRAME_FORMAT_NV12, 0, IA_CSS_FRAME_FORMAT_NV12 }, ~ ^~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/staging/media/atomisp/pci/atomisp_subdev.c:48:39: warning: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Wenum-conversion] { V4L2_MBUS_FMT_CUSTOM_NV12, 12, 12, IA_CSS_FRAME_FORMAT_NV12, 0, IA_CSS_FRAME_FORMAT_NV12 }, ~ ^~~~~~~~~~~~~~~~~~~~~~~~ ../drivers/staging/media/atomisp/pci/atomisp_subdev.c:47:34: warning: implicit conversion from enumeration type 'enum ia_css_frame_format' to different enumeration type 'enum atomisp_input_format' [-Wenum-conversion] { MEDIA_BUS_FMT_JPEG_1X8, 8, 8, IA_CSS_FRAME_FORMAT_BINARY_8, 0, ATOMISP_INPUT_FORMAT_BINARY_8 }, ~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ 5 warnings generated. > I'll try to apply your patch series on it, once I'll be able to > fix a bug with mmap support. It looks like all of them apply to your experimental branch aside from patch 3, which you handled in a different way. Cheers, Nathan
