[PATCH net-next] ath9k: Use static const

From: Joe Perches
Date: Fri Feb 21 2014 - 17:46:54 EST


Trivially reduces text size too.

$ size drivers/net/wireless/ath/ath9k/debug.o*
text data bss dec hex filename
34436 2528 5128 42092 a46c drivers/net/wireless/ath/ath9k/debug.o.new
34464 2528 5128 42120 a488 drivers/net/wireless/ath/ath9k/debug.o.old
