If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

All errors (new ones prefixed by >>, old ones prefixed by <<):

Thanks for reporting this problem. This issue has already been fixed by
Andrew [1][2] earlier.
This issue happens because the KUnit tests can be built and run as a
kernel module.
