Subject: [PATCH 2/3] regulator: axp20x: Handle regulator_register returning ENODEV
Date: Fri, 11 Mar 2016 22:01:08 +0100 [thread overview]
Message-ID: <1457730069-31760-2-git-send-email-hdegoede@redhat.com> (raw)
In-Reply-To: <1457730069-31760-1-git-send-email-hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
Handle regulator_register returning ENODEV, this may happen when
the dts node for the regulator contains "status = disabled" which
is useful for the ldo_io regulators, to avoid the regulator code
getting in the way of gpio use of these pins.
