Hi Weihang, I love your patch! Yet something to improve: [auto build test ERROR on rdma/for-next] [also build test ERROR on linus/master v5.7-rc3 next-20200424] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Weihang-Li/RDMA-core-Assign-the-name-of-device-when-allocating-ib_device/20200428-022647 base: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git for-next config: sh-allmodconfig (attached as .config) compiler: sh4-linux-gcc (GCC) 9.3.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree COMPILER_INSTALL_PATH=$HOME/0day GCC_VERSION=9.3.0 make.cross ARCH=sh If you fix the issue, kindly add following tag as appropriate Reported-by: kbuild test robot <lkp@xxxxxxxxx> All errors (new ones prefixed by >>): drivers/infiniband/sw/siw/siw_main.c: In function 'siw_device_register': >> drivers/infiniband/sw/siw/siw_main.c:70:7: error: too many arguments to function 'ib_register_device' 70 | rv = ib_register_device(base_dev, name); | ^~~~~~~~~~~~~~~~~~ In file included from drivers/infiniband/sw/siw/siw_main.c:20: include/rdma/ib_verbs.h:2781:5: note: declared here 2781 | int ib_register_device(struct ib_device *device); | ^~~~~~~~~~~~~~~~~~ drivers/infiniband/sw/siw/siw_main.c: In function 'siw_device_create': >> drivers/infiniband/sw/siw/siw_main.c:326:45: error: macro "ib_alloc_device" requires 3 arguments, but only 2 given 326 | sdev = ib_alloc_device(siw_device, base_dev); | ^ In file included from drivers/infiniband/sw/siw/siw_main.c:20: include/rdma/ib_verbs.h:2771: note: macro "ib_alloc_device" defined here 2771 | #define ib_alloc_device(drv_struct, member, name) \ | >> drivers/infiniband/sw/siw/siw_main.c:326:9: error: 'ib_alloc_device' undeclared (first use in this function); did you mean '_ib_alloc_device'? 326 | sdev = ib_alloc_device(siw_device, base_dev); | ^~~~~~~~~~~~~~~ | _ib_alloc_device drivers/infiniband/sw/siw/siw_main.c:326:9: note: each undeclared identifier is reported only once for each function it appears in vim +/ib_register_device +70 drivers/infiniband/sw/siw/siw_main.c bdcf26bf9b3acb Bernard Metzler 2019-06-20 63 bdcf26bf9b3acb Bernard Metzler 2019-06-20 64 static int siw_device_register(struct siw_device *sdev, const char *name) bdcf26bf9b3acb Bernard Metzler 2019-06-20 65 { bdcf26bf9b3acb Bernard Metzler 2019-06-20 66 struct ib_device *base_dev = &sdev->base_dev; bdcf26bf9b3acb Bernard Metzler 2019-06-20 67 static int dev_id = 1; bdcf26bf9b3acb Bernard Metzler 2019-06-20 68 int rv; bdcf26bf9b3acb Bernard Metzler 2019-06-20 69 bdcf26bf9b3acb Bernard Metzler 2019-06-20 @70 rv = ib_register_device(base_dev, name); bdcf26bf9b3acb Bernard Metzler 2019-06-20 71 if (rv) { bdcf26bf9b3acb Bernard Metzler 2019-06-20 72 pr_warn("siw: device registration error %d\n", rv); bdcf26bf9b3acb Bernard Metzler 2019-06-20 73 return rv; bdcf26bf9b3acb Bernard Metzler 2019-06-20 74 } bdcf26bf9b3acb Bernard Metzler 2019-06-20 75 sdev->vendor_part_id = dev_id++; bdcf26bf9b3acb Bernard Metzler 2019-06-20 76 bdcf26bf9b3acb Bernard Metzler 2019-06-20 77 siw_dbg(base_dev, "HWaddr=%pM\n", sdev->netdev->dev_addr); bdcf26bf9b3acb Bernard Metzler 2019-06-20 78 bdcf26bf9b3acb Bernard Metzler 2019-06-20 79 return 0; bdcf26bf9b3acb Bernard Metzler 2019-06-20 80 } bdcf26bf9b3acb Bernard Metzler 2019-06-20 81 :::::: The code at line 70 was first introduced by commit :::::: bdcf26bf9b3acb03c8f90387cfc6474fc8ac5521 rdma/siw: network and RDMA core interface :::::: TO: Bernard Metzler <bmt@xxxxxxxxxxxxxx> :::::: CC: Jason Gunthorpe <jgg@xxxxxxxxxxxx> --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx
