Merge tag 'staging-3.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver fixes from Greg Kroah-Hartman:
 "Here are some staging driver fixes for your 3.7-rc tree.

  Nothing major here, a number of iio driver fixups that were causing
  problems, some comedi driver bugfixes, and a bunch of tidspbridge
  warning squashing and other regressions fixed from the 3.6 release.

  All have been in the linux-next releases for a bit.

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