From 71ca46eeeff3273f6641ab3e30292d3d36f1d3be Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Wed, 9 Mar 2016 13:12:13 -0800 Subject: [PATCH] thermal: convert tegra_thermal to use devm_thermal_zone_of_sensor_register This changes the driver to use the devm_ version of thermal_zone_of_sensor_register and cleans up the local points and unregister calls.
