Subject: [PATCH v4 2/7] regulator: core: Refactor regulator_list_voltage()
Date: Mon, 22 Jan 2018 15:30:07 +0100	[thread overview]
Message-ID: <1516631412-17542-3-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1516631412-17542-1-git-send-email-m.purski@samsung.com>

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.
