From: Thomas Hebb <tommyhebb@xxxxxxxxx> commit 4008bc7d39537bb3be166d8a3129c4980e1dd7dc upstream. 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.
