From 4008bc7d39537bb3be166d8a3129c4980e1dd7dc Mon Sep 17 00:00:00 2001 From: Thomas Hebb Date: Sat, 23 Jan 2021 18:46:08 -0800 Subject: [PATCH] hwmon: (dell-smm) Add XPS 15 L502X to fan control blacklist MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It has been reported[0] that the Dell XPS 15 L502X exhibits similar freezing behavior to the other systems[1] on this blacklist. The issue was exposed by a prior change of mine to automatically load dell_smm_hwmon on a wider set of XPS models. To fix the regression, add this model to the blacklist.
