I tried to reproduce has instructed, the log is full of warnings and the compilation eventually fails to link. It seems that most (if not all) drivers with a MODULE_DEVICE_TABLE() show this warning with the provided .config (COMPILE_TEST). When compiled with gcc, no such warning is shown. I can remove COMPILE_TEST for this driver, it will make the warning go away but I'm not sure it is appropriate. > > --- > 0-DAY CI Kernel Test Service, Intel Corporation > https://lists.01.org/hyperkitty/list/kbuild-...@lists.01.org
