There's an ongoing movement to eventually enable the -Wformat flag for
clang. Previous patches have targeted incorrect usage of
format specifiers. In this case, however, the "incorrect" format
specifiers are intrinsically part of the test cases. Hence, fixing them
would be misaligned with their intended purpose. My proposed fix is to
simply disable the warnings so that one day a clean build of the kernel
with clang (and -Wformat enabled) would be possible. It would also keep
us in the green for alot of the CI bots.

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.
