KUnit's assertion macros have variants which accept a printf format
string, to allow tests to specify a more detailed message on failure.
These (and the related KUNIT_FAIL() macro) ultimately wrap the
__kunit_do_failed_assertion() function, which accepted a printf format
specifier, but did not have the __printf attribute, so gcc couldn't warn
on incorrect agruments.

It turns out there were quite a few tests with such incorrect arguments.

Add the __printf() specifier now that we've fixed these errors, to
prevent them from recurring.

History
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.
