'ar9170_qmap' is used in some source files which include carl9170.h, but not all of them. A 'defined but not used' warning is thrown when compiling the ones which do not use it. Fixes the following W=1 kernel build warning(s) from drivers/net/wireless/ath/carl9170/carl9170.h:57, In file included from drivers/net/wireless/ath/carl9170/carl9170.h:57, drivers/net/wireless/ath/carl9170/carl9170.h:71:17: warning: ‘ar9170_qmap’ defined but not used [-Wunused-const-variable=] NB: Snipped - lots of these repeat Cc: Christian Lamparter <chunkeey@googlemail.com> Cc: Kalle Valo <redacted> Cc: "David S.
