Pull regulator updates for 3.4 from Mark Brown:
 "This has been a fairly quiet release from a regulator point of view,
  the only real framework features added were devm support and a
  convenience helper for setting up fixed voltage regulators.

  We also added a couple of drivers (but will drop the BQ240022 driver
  via the arm-soc tree as it's been replaced by the more generic
  gpio-regulator driver) and Axel Lin continued his relentless and
  generally awesome stream of fixes and cleanups."
