Hi John,

Why the RESEND?

Please update your subject to be less than 72 characters or so. It needs to
display completely with git log on an 80 char terminal without getting
truncated. Anything you can't fit there, please add to the changelog below.

Please read Documentation/stable-kernel-rules.txt for how to submit changes to
the stable kernels.

Generally speaking, if you wrote it, I expect you have tested it :-) This isn't
bad, but not really necessary. It would be more useful to include a cover letter
with more verbage on what specifically you tested. Both Lenovo laptops listed
below? Any others to ensure no regressions? Etc. This is a trivial patch, so I'm
not particularly concerned, just as an example.

Please correct the commit message and resubmit as v2.
