Please compile any files modified by your proposed
changes _before_ you
submit them.

For instance:

$ git grep -w RTW_WPA_OUI drivers/staging/rtl8723bs/core/rtw_ap.c
drivers/staging/rtl8723bs/core/rtw_ap.c:extern unsigned char RTW_WPA_OUI[];
drivers/staging/rtl8723bs/core/rtw_ap.c:        if (!memcmp(RTW_WPA_OUI, oui, 4))
