Thank you!

And this might be a problem in my current process when handing off
to others.  I normally don't run checkpatch until just before a send
out the patches, which means that none of the commits I handed off to
you guys had been checkpatched.  There was I time I tried a checkpatch
hook in git, but the false-positive rate made that a non-starter.
