Have you checked your problem exists in the latest upstream kernel ?

If you are resolving issue with kernel 3.12 -  it's likely a thing for your 
distribution and its maintenance support?

Upstream (and this is upstream ml) is close to release 4.1 kernel - so you are 
fixing couple years old issue? What kind of action do you expect ?
