Despite the bug exists and the patch is fixing it, it is really unlikely
to happen regularly unless the hw has wrong FW. OTOH it is pretty useful
during development of platform code to spot and fix errors and typos
faster. I don't think there's need to go to 3.13. It can be applied for
next version after the patch set I sent it in reply to.
