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.
