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> | Closes: https://lore.kernel.org/oe-kbuild-all/202407081638.r5xQjyqM-lkp@intel.com/ Note: the openeuler/OLK-6.6 HEAD 01c2a11a75f4f8b273ef3e34cca3974b10314a3a builds fine.
