[PATCH v3 00/10] platform/x86: alienware-wmi-wmax: HWMON support + DebugFS + Improvements

From: Kurt Borja
Date: Wed Mar 05 2025 - 19:58:12 EST


Hi all,

This set mainly adds hwmon and manual fan control support (patches 7-8)
to the alienware-wmi driver, after some improvements.

Aside from some minor changes Ilpo commented on, I added inline helpers
for most awcc operations to make those calls more compact.

Thank you for your feedback :)
