My opinion is that this approach is not a good approach to solving the
problem.  It is papering over a symptom, instead of dealing with the
root cause.

But despite my opinion, you can add to patches 2-4 (I did not test
the self-test added in patch 1):

   Tested-by: Frank Rowand <frank.rowand@sonymobile.com>

The patches resolve the name conflict originally reported for the
qcomm PMIC, tested on 3.15-rc1, with a bunch of out of tree
patches.
