I suspect that you would have just explained "since there is only
one caller, let's open-code it" in the log message, without making
this a two-patch series, and that would also have been perfectly
understandable (and in this case probably preferrable).
So the patch text would be OK; it was surprising to have the change
without being explained, that's all.
Thanks.
