Note this checkpatch warning though:

ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit 0123456789ab ("commit description")'
#40:

It is also common to add a "Fixes:" line with that information so that
patch backporting can be automated. And as I said before I would tag
the patch for stable as well.
