  The set_trip_temp() callback is used when changing the trip temperature
through sysfs. As it is called with the thermal-zone-device lock held
it must not use thermal_zone_get_trip() directly or it will deadlock.

Fixes: 56d7b397cc29 ("thermal/drivers/tegra: Use generic thermal_zone_get_trip() function")
