It makes sense to keep it in struct edac_raw_error_desc as the function interface of edac_raw_mc_handle_error() becomes easier. There is no reason to have a function argument for the type while all other error data is in edac_raw_error_desc. This change might look trivial, but this series contains many small changes like this and in the end there is a reasonable change of the function that describes it much better: void edac_raw_mc_handle_error(struct edac_raw_error_desc *e, struct dimm_info *dimm); ... that reads as handle error described in e that affects this dimm. -Robert
