Thanks for renumbering these cooling maps.  It's just that you
missed to label this patch as the v2, i.e. you should have used
"[PATCH v2]" in the patch subject.

Please, resend this patch with the v2 label, and please provide
a change log in the patch notes, i.e. below the "---" line.

Here's an example of an earlier v2 patch submission [1] that you
