[PATCH RFC 0/2] regulator: qcom_smd: Disable unused regulators

[Stephan Gerhold]

At the moment unused regulators managed by the RPM firmware on Qualcomm
platforms stay on forever if they are already on during boot. This is
because we have no way of checking if they are really on or not.

Fix this by sending an explicit disable request for all unused
regulators managed by the qcom_smd-regulator driver.

I'm sending this as RFC mainly for the change in the regulator core.
There is also a slight chance of breakage for incomplete device trees
that mistakenly rely on having unused regulators always-on.
