+Subject: [PATCH] ath9k: Remove some #defined constants to decrease
+ verbosity
+
+The removed ATH9K_SLOT_TIME_X constants simply map the value in microseconds
+to the same integer. These constants were not used consistently, so fix the
+inconsistency issue by replacing all occurances with the integer equivalent.
