Merge tag 'regulator-fix-v4.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "Two fixes here, one device specific fix for axp20x and a core fix for
   cases where one regulator is supplying another which broke probe
  deferral, substituting in a dummy regulator too aggressively"

* tag 'regulator-fix-v4.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: core: Handle probe deferral from DT when resolving supplies
  regulator: axp20x: Fix enable bit indexes for DCDC4 and DCDC5
