When we went through the make file of mac80211, it is seen that the only 
when CONFIG_MAC80211_DEBUGFS macro is enabled, the files debugfs.c, 
debugfs_sta.c, debugfs_netdev.c, debugfs_key.c are compiled in.

So it may not be required to wrap up any piece of code in these files 
are they will not be compiled in the first place when the macro 
CONFIG_MAC80211_DEBUGFS is disabled.
Let me know your thoughts on this.
