Subject[PATCH 5.4 069/104] Input: sun4i-ts - add a check for devm_thermal_zone_of_sensor_register
Date
From: Chuhong Yuan <hslester96@gmail.com>

commit 97e24b095348a15ec08c476423c3b3b939186ad7 upstream.

The driver misses a check for devm_thermal_zone_of_sensor_register().
Add a check to fix it.

Fixes: e28d0c9cd381 ("input: convert sun4i-ts to use devm_thermal_zone_of_sensor_register")
