Merge tag 'regulator-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A respin of the merges in the previous pull request with one extra
  fix.

  A quiet release for the regulator API, quite a large number of small
  improvements all over but other than the addition of new drivers for
  the AS3722 and MAX14577 there is nothing of substantial non-local
  impact"
