Looks okay to me:

I've told you about this before:

"
Please don't do that.

If you think your patch has been missed, then please send it again as
a [RESEND].  In this case you will need to fix the $SUBJECT line too.
To see what it should look like do the following:
 
  `git log --oneline -- drivers/mfd`
 
Once fixed, s/[PATCH]/[RESEND/ and resubmit it.
"

In this case the $SUBJECT line is fine, but the rest is relevant.
