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
