[PATCH v3 1/4] platform/x86/uniwill: uniwill-laptop: Rework hwmon feature defines
From: Werner Sembach
Date: Fri Feb 27 2026 - 15:12:14 EST
From: Armin Wolf <W_Armin@xxxxxx>
Split hwmon feature define in smaller parts to accommodate for diverse
hardware. You can now specify the presence of a cpu and/or a gpu temp
sensor separately and if one or 2 fans exists.
