Merge tag 'regulator-v3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "A few small fixes:

   - Fixes for bugs in Palmas and as3722 exposed by recent changes in
     the core - the drivers weren't allowing the current configuration
     to be read sometimes.
   - Provide a stub for regulator_can_change_voltage() for !REGULATOR.
   - Make sure ltc3589 only looks at its child nodes in the device tree
     rather than searching the whole tree"

* tag 'regulator-v3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: ltc3589: Use of_get_child_by_name
  regulator: palmas: Fix SMPS list for 0V
  regulator: add regulator_can_change_voltage stub
  regulator: as3722: Make 0 a valid selector
