From 2757269a7defe96e871be795b680b602efb877ce Mon Sep 17 00:00:00 2001 From: Armin Wolf Date: Thu, 29 Jul 2021 00:15:57 +0200 Subject: [PATCH] hwmon: (dell-smm-hwmon) Fix fan mutliplier detection for 3rd fan There are up to three fans, but the detection omits the 3rd one. Fix that by using DELL_SMM_NO_FANS.
