Subject[PATCH 4.19 005/113] hwmon: (pwm-fan) Disable PWM if fetching cooling data fails
Date
From: Stefan Wahren <stefan.wahren@i2se.com>

commit 53f1647da3e8fb3e89066798f0fdc045064d353d upstream.

In case pwm_fan_of_get_cooling_data() fails we should disable the PWM
just like in the other error cases.

Fixes: 2e5219c77183 ("hwmon: (pwm-fan) Read PWM FAN configuration from device tree")
