Subject: regulator: core: Refactor regulator_list_voltage()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3d67fe950707a930664c5673ecc026f1bb497136;p=openwrt%2Fstaging%2Fblogic.git

regulator: core: Refactor regulator_list_voltage()

Change _regulator_list_voltage() argument from regulator to
regulator_dev in order to provide better separation of core layers.
Allow calling _regulator_list_voltage() from functions, with
regulator_dev argument. This refactoring is needed in order to
implement setting voltage of coupled regulators.
