kind of redundant statement considering the summary ...

you should really be using git to generate patches and send e-mails. also, signed-off-by (and similar tags) use real addresses, not munged ones. -mike

Please use a valid e-mail address (hint - it should have an @ sign). You may want to provide a brief description of the controller here.

It's best to use git tools to generate the patch. If you use git-send-email you're more-or-less guaranteed to avoid line-wrapping issues.
