Merge tag 'char-misc-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver merge from Greg Kroah-Hartman:
 "Here is the "big" char/misc driver tree update for the 3.7-rc1 merge
  window.

  Nothing major, just a number of driver updates and fixes, all of which
  have been in the linux-next releases for a while now either in my
  tree, or in Andrew's (the lis3l driver changes came from his tree last
  week).

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
