Subject: [PATCH 2/2] regulator: axp20x: Handle regulator_register returning ENODEV
Date: Wed, 27 Apr 2016 16:03:45 +0200 [thread overview]
Message-ID: <1461765825-15915-3-git-send-email-hdegoede@redhat.com> (raw)
In-Reply-To: <1461765825-15915-1-git-send-email-hdegoede@redhat.com>
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.
