Subject: [PATCH] hwmon: (adt7475) Fix default duty on fan is disabled
Date: Mon,  1 Jul 2024 15:32:52 +0800	[thread overview]
Message-ID: <20240701073252.317397-1-chineweff@gmail.com> (raw)

According to the comments on fan is disabled, we change to manual mode
and set the duty cycle to 0.
For setting the duty cycle part, the register is wrong. Fix it.
