char-misc

Pull char/misc fix from Greg KH:
 "Here is a single patch, that fixes up a commit that came in the
  previous char/misc merge.

  It fixes a bug in the hpet driver that everyone keeps tripping over in
  their automated testing. Good thing is, people are catching it. Bad
  thing it wasn't caught by anyone testing before this. Oh well...

  This has been in linux-next for a few days with no reported issues"
