The commit message doesn't live up to our standards:
 - The subject should be prefixed with the subsystem name,
   and it should explain briefly what the patch does
 - The commit message body should be more thorough - what
   you're fixing, what happens without your patch
 - A bullet-point list of one item is pointless
 - We don't add signed-off-by tag

I fixed it this time and pushed.

Please read the 'How to write a commit message' section of the developer
guide and try to comply:
