Subject: [PATCH 2/6] hwmon: (aspeed-pwm-tacho) Use devm_thermal_of_cooling_device_register
Date:   Thu, 18 Apr 2019 12:58:16 -0700
Message-Id: <1555617500-10862-3-git-send-email-linux@roeck-us.net>
In-Reply-To: <1555617500-10862-1-git-send-email-linux@roeck-us.net>
References: <1555617500-10862-1-git-send-email-linux@roeck-us.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use devm_thermal_of_cooling_device_register() to register the cooling
device. As a side effect, this fixes a driver bug:
thermal_cooling_device_unregister() was not called on removal.

Fixes: f198907d2ff6d ("hwmon: (aspeed-pwm-tacho) cooling device support.")
