In rtw_mlme_ext.c, nested #ifdef blocks form the following structure inside the file: #ifdef CONFIG_8723AU_AP_MODE (line 1323) [...] #ifdef CONFIG_8723AU_AP_MODE (line 1720) [...] #endif (2 more ifdef blocks with CONFIG_8723AU_AP_MODE follow) [...] #endif /* CONFIG_8723AU_AP_MODE */ (line 1763) The inner #ifdefs are unnecessary as they depend on the same condition as the outer #ifdef and can thus be removed.
