From cf7559bc053471f32373d71d04a9aa19e0b48d59 Mon Sep 17 00:00:00 2001 From: Brian Carnes Date: Thu, 12 Dec 2013 08:05:32 +0100 Subject: hwmon: (w83l786ng) Fix fan speed control mode setting and reporting The wrong mask is used, which causes some fan speed control modes (pwmX_enable) to be incorrectly reported, and some modes to be impossible to set.
