Subject: [PATCH 3/5] leds: lm3692x: Handle failure to probe the regulator
Date: Tue, 17 Sep 2019 19:19:56 -0700 [thread overview]
Message-ID: <8491e5df20f4672a242c9072f58c243291cfe752.1568772964.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1568772964.git.agx@sigxcpu.org>
Instead use devm_regulator_get_optional since the regulator
is optional and check for errors.
