No, that would add extra complexity at the drivers level just due to debug messages. I think that the better is to move this printk to the debug-specific routine that is called only when the dimm is filled (edac_mc_dump_dimm). With this cange, the message will be printed only for the filled dimms. This is a cleanup patch, so I'll write it, together with the change that will get rid of the loop that uses KERN_CONT. It will use a function added by a latter patch at edac_mc_sysfs so it can't be merged on this patch anyway.
