Merge tag 'regulator-v4.19-rc5' into regulator-bd718xx
regulator: Fixes for 4.19 A collection of fairly minor bug fixes here, a couple of driver specific ones plus two core fixes. There's one fix for the new suspend state code which fixes some confusion with constant values that are supposed to indicate noop operation and another fixing a race condition with the creation of sysfs files on new regulators.
