Subject: [PATCH] thermal: broadcom: use devm_thermal_zone_of_sensor_register
Date: Tue, 30 Oct 2018 17:08:51 +0100	[thread overview]
Message-ID: <1540915731-22312-1-git-send-email-Julia.Lawall@lip6.fr> (raw)

Using devm_thermal_zone_of_sensor_register allows to simplify some
error handling code, drop a label, and drop the remove function.

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
