Hi Kory, kernel test robot noticed the following build warnings: [auto build test WARNING on net-next/main] url: https://github.com/intel-lab-lkp/linux/commits/Kory-Maincent/ethtool-Expand-Ethernet-Power-Equipment-with-c33-PoE-alongside-PoDL/20231202-021033 base: net-next/main patch link: https://lore.kernel.org/r/20231201-feature_poe-v2-2-56d8cac607fa%40bootlin.com patch subject: [PATCH net-next v2 2/8] ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL reproduce: (https://download.01.org/0day-ci/archive/20231206/202312061223.iHikO4O3-lkp@xxxxxxxxx/reproduce) 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@xxxxxxxxx> | Closes: https://lore.kernel.org/oe-kbuild-all/202312061223.iHikO4O3-lkp@xxxxxxxxx/ All warnings (new ones prefixed by >>): >> Documentation/networking/pse-pd/introduction.rst:56: WARNING: Title underline too short. vim +56 Documentation/networking/pse-pd/introduction.rst 46 47 - For general PSE (PoE) code, use "c33_pse" key words. For example: 48 ``enum ethtool_c33_pse_admin_state c33_admin_control;``. 49 This aligns with Clause 33, encompassing various PoE forms. 50 51 - For PoDL PSE - specific code, use "podl_pse". For example: 52 ``enum ethtool_podl_pse_admin_state podl_admin_control;`` to differentiate 53 PoDL PSE settings according to Clause 104. 54 55 Summary of Clause 33: Data Terminal Equipment (DTE) Power via Media Dependent Interface (MDI) > 56 ------------------------------------------------------------------------------------------- 57 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
