+Subject: [PATCH 1/2] ath9k: move spectral scan support under a separate config
+ symbol
+
+At the moment, spectral scan support, and with it RELAY, is always enabled
+with ATH9K[_HTC]_DEBUGFS. Spectral scan support is currently the only user
+of RELAY in ath9k, and it unconditionally reserves a relay channel.
+
+Having debugfs support in ath9k is often useful even on very small embedded
+routers, where we'd rather like to avoid the code size and RAM usage of the
+relay support.
