[PATCH] regulator: core: Fix voltage change propagations to supply regulators
From: Tirupathi Reddy
Date: Thu May 25 2017 - 06:03:17 EST
Some regulators support get_voltage() and some support get_voltage_sel()
operations but currently we only propagate changes if the regulator has
a get_voltage() operation. Also do this if we've got get_voltage_sel()
