I'm not convinced that there is a clear expectation here, any change will doubtless upset some other user (for example someone using a system derived from a reference board that happens to work with it's device tree, or something where the firmware puts discovered information into DMI). Really you're just not supposed to combine DMI and DT based discovery methods, having a system shipping both is just going to lead to confusion and there's no way we can possibly get it right. You have decided that for your systems the DMI information is bad and you want to override it but that doesn't mean that the next person won't make the opposite choice. Any decision here should be policy based in userspace based on the full system information. Please don't send content free pings and please allow a reasonable time for review. People get busy, go on holiday, attend conferences and so on so unless there is some reason for urgency (like critical bug fixes) please allow at least a couple of weeks for review. If there have been review comments then people may be waiting for those to be addressed. Sending content free pings adds to the mail volume (if they are seen at all) which is often the problem and since they can't be reviewed directly if something has gone wrong you'll have to resend the patches anyway, so sending again is generally a better approach though there are some other maintainers who like them - if in doubt look at how patches for the subsystem are normally handled.
