ERROR: modpost: "__tracepoint_iwlmei_me_msg" [drivers/net/wireless/intel/iwlwifi/mei/iwlmei.ko] undefined!

ERROR: modpost: "__tracepoint_iwlmei_sap_data" [drivers/net/wireless/intel/iwlwifi/mei/iwlmei.ko] undefined! Use the same macro incantation that is used in the main iwlwifi driver to leave out the tracing when CONFIG_IWLWIFI_DEVICE_TRACING is disabled.
