From 39b24cced70fdc336dbc0070f8b3bde61d8513a8 Mon Sep 17 00:00:00 2001 From: Wayne Tung Date: Mon, 1 Jul 2024 15:32:52 +0800 Subject: [PATCH] hwmon: (adt7475) Fix default duty on fan is disabled 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.
