Subject: [PATCH] Input: sun4i-ts - add a check for devm_thermal_zone_of_sensor_register
Date: Tue, 10 Dec 2019 17:14:01 +0800	[thread overview]
Message-ID: <20191210091401.23388-1-hslester96@gmail.com> (raw)

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")
