Subject: [PATCH] platform/x86: asus-nb-wmi: add quirk_asus_ignore_fan for UX3405MA
Date: Sun, 21 Dec 2025 22:01:48 +0100 [thread overview]
Message-ID: <20251221210218.12274-1-timwassink.dev@gmail.com> (raw)
The ASUS Zenbook 14 (UX3405MA) uses a newer WMI interface for thermal
management that does not support the legacy WMI fan control methods.
Currently, this results in ENODEV (-19) errors in dmesg when the driver
attempts to fetch factory fan curve defaults.
Add a quirk to use quirk_asus_ignore_fan to silence these errors and
signal that legacy fan control is intentionally unsupported, as thermal
policies are handled through the platform_profile interface.
