…kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "Mostly driver specific fixes here, though one of them uncovered the
  issue Stephen Warren fixed with multiple OF matches getting upset due
  to a lack of cleanup."

* tag 'regulator-v3.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: s2mps11: fix incorrect register for buck10
  regulator: clear state each invocation of of_regulator_match
  regulator: max8997: Fix using wrong dev argument at various places
  regulator: max77686: Fix using wrong dev argument at various places
  regulator: max8907: Fix using wrong dev argument for calling of_regulator_match
  regulator: max8998: fix incorrect min_uV value for ldo10
  regulator: tps65910: Fix using wrong dev argument for calling of_regulator_match
  regulator: tps65217: Fix using wrong dev argument for calling of_regulator_match
