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.
