fan_curve_check_present() probes for fan curve support by calling
fan_curve_get_factory_default(). On devices whose firmware does not
implement the fan curve WMI methods (e.g. the ASUS-built Intel
NUC15CRHU5), the underlying asus_wmi_evaluate_method_buf() returns
-ENODEV, which fan_curve_get_factory_default() reports with pr_warn()
on every boot:

  asus_wmi: fan_curve_get_factory_default (0x00110024) failed: -19
  asus_wmi: fan_curve_get_factory_default (0x00110025) failed: -19
  asus_wmi: fan_curve_get_factory_default (0x00110032) failed: -19

This is a normal, expected condition: the caller already handles the
absence gracefully, and asus_wmi_evaluate_method_buf() already logs the
unsupported method at pr_debug() level. Suppress the warning for -ENODEV
while keeping it for genuine failures.

Hi,

This duplicates an earlier patch by Armandas Kvietkus:

  https://lore.kernel.org/all/20260503174752.26288-1-armundunelis@gmail.com/

I missed it before sending, sorry for the noise. Ilpo already reviewed
that patch and suggested using pr_debug() instead, so please disregard
this patch.

Thanks,
HyeongJun
