Merge tag 'regulator-v3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown:
"A small set of driver fixes plus one larger core change which changes
the way we check to see if we're using DT so that there aren't any
races between deciding we're using DT and the regulator subsystem
noticing.
This makes the new support for substituting a dummy regulator and
optional regulators work a lot better on DT systems since it ensures
that we don't trigger probe deferral when we shouldn't which was
causing bugs in clients"
* tag 'regulator-v3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
regulator: pfuze100: allow misprogrammed ID
regulator: pfuze100: Fix address of FABID
regulator: as3722: set the correct current limit
regulator: core: Check for DT every time we check full constraints
regulator: core: Replace checks of have_full_constraints with a function
