This is the third time this set of macros has entered the kernel:
drivers/net/wireless/rtlwifi/btcoexist/halbtcoutsrc.h
drivers/staging/rtl8192ee/btcoexist/halbtcoutsrc.h
drivers/staging/rtl8821ae/btcoexist/halbtcoutsrc.h
Can we extract these macros to some common place and keep them from returning?
