Hi Oliver, kernel test robot noticed the following build errors: [auto build test ERROR on staging/staging-testing] url: https://github.com/intel-lab-lkp/linux/commits/Oliver-Crumrine/staging-octeon-clean-up-the-octeon-ethernet-driver/20230828-051802 base: staging/staging-testing patch link: https://lore.kernel.org/r/PH7PR11MB7643F9F5DBB6781022CC4F4DBCE1A%40PH7PR11MB7643.namprd11.prod.outlook.com patch subject: [PATCH 6/6] staging: octeon: clean up the octeon ethernet driver config: s390-randconfig-001-20230828 (https://download.01.org/0day-ci/archive/20230828/202308280752.Jl0Lli0C-lkp@xxxxxxxxx/config) compiler: clang version 15.0.7 (https://github.com/llvm/llvm-project.git 8dfdcc7b7bf66834a761bd8de445840ef68e4d1a) reproduce: (https://download.01.org/0day-ci/archive/20230828/202308280752.Jl0Lli0C-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/202308280752.Jl0Lli0C-lkp@xxxxxxxxx/ All errors (new ones prefixed by >>): In file included from drivers/staging/octeon/ethernet.c:11: In file included from include/linux/netdevice.h:38: In file included from include/net/net_namespace.h:43: In file included from include/linux/skbuff.h:28: In file included from include/linux/dma-mapping.h:11: In file included from include/linux/scatterlist.h:9: In file included from arch/s390/include/asm/io.h:75: include/asm-generic/io.h:547:31: warning: performing pointer arithmetic on a null pointer has undefined behavior [-Wnull-pointer-arithmetic] val = __raw_readb(PCI_IOBASE + addr);
