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
| Reported-by: kernel test robot <lkp@intel.com>

Note: the linux-next/master HEAD 20d5c66e1810e6e8805ec0d01373afb2dba9f51a builds fine.
It may have been fixed somewhere.
