This will produce different ids if there are two mtd chips. E.g.: Before patches: 0 - first chip partition 1 - second chip partition After patches: 0 - first chip partition 1 - first chip master 2 - second chip partition 3 - second chip master Or we should manually give region for master's ids at the end of idr range near UINT_MAX. And that requires careful manual handling of overflows. Personally, I think it is bad idea to rely on partition number, but it is the status-quo now. - - Thanks, Sasha
