Merge tag 'for-v3.6' of git://git.infradead.org/battery-2.6

Pull battery updates from Anton Vorontsov:
 "The tag contains just a few battery-related changes for v3.6.  It's is
  all pretty straightforward, except one thing.

  One of our patches added thermal support for power supply class, but
  thermal/ subsystem changed under our feet.  We (well, Stephen, that
  is) caught the issue and it was decided[1] that I'd just delay the
  battery pull request, and then will fix it up by merging upstream back
  into battery tree at the specific commit.

  That's not all though: another[2] small fixup for thermal subsystem
  was needed to get rid of a warning in power supply subsystem (the
  warning was not drivers/power's "fault", the thermal registration
  function just needed a proper const annotation, which is also done by
  a small commit on top of the merge.

  So, to sum this up:
   - The 'master' branch of the battery tree was in the -next tree for
     weeks, was never rebased, altered etc.  It should be all OK;
   - Although, for-v3.6 tag contains the 'master' branch + merge + the
     warning fix.
