Subject: [PATCH] leds: an30259a: add a check for devm_regmap_init_i2c
Date: Wed, 16 Oct 2019 20:06:07 +0800 [thread overview]
Message-ID: <20191016120607.32718-1-hslester96@gmail.com> (raw)
an30259a_probe misses a check for devm_regmap_init_i2c and may cause
problems.
Add a check and print errors like other leds drivers.
