The fan curve control patches introduced a regression for at least the TUF FX506 and possibly other TUF series laptops that do not have support for fan curve control. As part of the probing process, asus_wmi_evaluate_method_buf is called to get the factory default fan curve . The WMI management function returns 0 on certain laptops to indicate lack of fan curve control instead of ASUS_WMI_UNSUPPORTED_METHOD. This 0 is transformed to -ENODATA which results in failure when probing.
