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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
