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.
