Merge tag 'regulator-fix-v4.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "A small collection of driver specific fixes for the regulator
  subsysetem:

   - Fix handling of probe deferral for GPIO regulators

   - Fix a typo in the module alias for DA9053

   - Fix the definition of BUCK9 in the S2MPS11 driver.  This change
     looks larger than it is because an irregularity in the hardware
     means that the macro used to define bucks 6-10 needs duplicating
     and tweaking to have a separate macro for 9

   - Fix a series of errors in the definitions of the LDOs the AXP20x
     regulators, some of which had always been present and some of which
     were introduced in the merge window"
