The kernel test robot reports undefined reference after we report wakeup reason to mac80211. This is because CONFIG_PM is not defined in the testing configuration file. In fact, functions within wow.c are used if CONFIG_PM is defined, so use CONFIG_PM to decide whether we build this file or not. The reported messages are: hppa-linux-ld: drivers/net/wireless/realtek/rtw88/wow.o: in function `rtw_wow_show_wakeup_reason': >> (.text+0x6c4): undefined reference to `ieee80211_report_wowlan_wakeup' >> hppa-linux-ld: (.text+0x6e0): undefined reference to `ieee80211_report_wowlan_wakeup' Reported-by: kernel test robot <lkp@xxxxxxxxx> Signed-off-by: Ping-Ke Shih <pkshih@xxxxxxxxxxx> --- drivers/net/wireless/realtek/rtw88/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/realtek/rtw88/Makefile b/drivers/net/wireless/realtek/rtw88/Makefile index c0e4b111c8b4..73d6807a8cdf 100644 --- a/drivers/net/wireless/realtek/rtw88/Makefile +++ b/drivers/net/wireless/realtek/rtw88/Makefile @@ -15,9 +15,9 @@ rtw88_core-y += main.o \ ps.o \ sec.o \ bf.o \ - wow.o \ regd.o +rtw88_core-$(CONFIG_PM) += wow.o obj-$(CONFIG_RTW88_8822B) += rtw88_8822b.o rtw88_8822b-objs := rtw8822b.o rtw8822b_table.o -- 2.25.1
