Subject: [PATCH] hwmon: (dell-smm) Add XPS 15 L502X to fan control blacklist
Date: Sat, 23 Jan 2021 18:46:08 -0800 [thread overview]
Message-ID: <a09eea7616881d40d2db2fb5fa2770dc6166bdae.1611456351.git.tommyhebb@gmail.com> (raw)
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.
