From 1da47a5a1f4a771d39dfe2e2aafd172b8bac68bf 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 [ Upstream commit 39b24cced70fdc336dbc0070f8b3bde61d8513a8 ] 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.
