Linus Torvalds 4b24ff7110 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.
