Hi Sergei,

Yes, strictly speaking I could have been more verbose & elaborated in
the changelog on every aspect of the simple change from "rtc:
mc146818@70" to "rtc@70". I didn't, but as it's obviously clear to you
what changed and it has no effect on either the code or the commit that
would end up in git I don't really see the point of your bringing it up.

Thanks,
    Paul
