Commit "tools/testing/cxl: Add XOR Math support to cxl_test" added a module parameter to cxl_test for the interleave_arithmetic option. In doing so, it also added this dev_dbg() message describing which option cxl_test used during load: "[ 111.743246] (NULL device *): cxl_test loading modulo math option" That "(NULL device *)" has raised needless user concern. Remove the dev_dbg() message and make the module_param readable via sysfs for users that need to know which math option is active.

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.
