Merge tag 'staging-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging drivers patches from Greg KH:
 "Here's the big staging driver tree update for 3.20-rc1.

  Lots of little things in here, adding up to lots of overall cleanups.
  The IIO driver updates are also in here as they cross the staging tree
  boundry a lot.  I2O has moved into staging as well, as a plan to drop
  it from the tree eventually as that's a dead subsystem.

  All of this has been in linux-next with no reported issues for a
  while"
