Ug. Let me guess, is this compiled with -Werror? Because a warning about a macro that may or may not create printf formatting, where gcc thinks it needs a gcc printf attribute and warns about it, is not something to fail the build on. For any build that fails on warnings, that specific warning needs to be silenced. I mean, "-Werror=suggest-attribute=format", really? -- Steve > > > >> > >> tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master > >> head: e35184f321518acadb681928a016da21a9a20c13 > >> commit: c7c37bb87590886e08d24dec53089f74b89f5fbb tracing/iwlwifi: Use the new __vstring() helper > >> date: 3 months ago > >> config: x86_64-sof-customedconfig-edison-defconfig > >> compiler: gcc-11 (Debian 11.3.0-8) 11.3.0 > >> reproduce (this is a W=1 build): > >> # https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c7c37bb87590886e08d24dec53089f74b89f5fbb > >> git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git > >> git fetch --no-tags linus master > >> git checkout c7c37bb87590886e08d24dec53089f74b89f5fbb > >> # save the config file > >> mkdir build_dir && cp config build_dir/.config > >> make W=1 O=build_dir ARCH=x86_64 SHELL=/bin/bash drivers/net/wireless/intel/iwlwifi/ > >> > >> If you fix the issue, kindly add following tag where applicable > >> | Reported-by: kernel test robot > >> > >> All errors (new ones prefixed by >>): > >> > >> In file included from include/trace/define_trace.h:102, > >> from drivers/net/wireless/intel/iwlwifi/iwl-devtrace-msg.h:71, > >> from drivers/net/wireless/intel/iwlwifi/iwl-devtrace.h:91, > >> from drivers/net/wireless/intel/iwlwifi/iwl-devtrace.c:15: > >> drivers/net/wireless/intel/iwlwifi/./iwl-devtrace-msg.h: In function 'trace_event_get_offsets_iwlwifi_dbg': > >>>> include/trace/trace_events.h:261:16: error: function 'trace_event_get_offsets_iwlwifi_dbg' might be a candidate for 'gnu_printf' format attribute [-Werror=suggest-attribute=format] > >> 261 | struct trace_event_raw_##call __maybe_unused *entry; \ > >> | ^~~~~~~~~~~~~~~~ > >> include/trace/trace_events.h:40:9: note: in expansion of macro 'DECLARE_EVENT_CLASS' > >> 40 | DECLARE_EVENT_CLASS(name, \ > >> | ^~~~~~~~~~~~~~~~~~~ > >> drivers/net/wireless/intel/iwlwifi/./iwl-devtrace-msg.h:49:1: note: in expansion of macro 'TRACE_EVENT' > >> 49 | TRACE_EVENT(iwlwifi_dbg, > >> | ^~~~~~~~~~~
