Subject: [PATCH v3 3/5] leds: lm3692x: Handle failure to probe the regulator
Date: Sat, 21 Sep 2019 14:12:10 -0700 [thread overview]
Message-ID: <32fd08565f8dff39ce9a13f7b0a2546d22913b3a.1569100154.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1569100154.git.agx@sigxcpu.org>
Instead use devm_regulator_get_optional since the regulator
is optional and check for errors.
