+Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
+ config symbol
+
+At the moment, spectral scan support, and with it RELAY, is always enabled
+with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
+RELAY in ath10k, and it unconditionally reserves a relay channel.
+
+Having debugfs support in ath10k 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. While ath10k-based devices usually have more
+resources than ath9k-based ones, it makes sense to keep the configuration
+symmetric to ath9k, so the same base kernel without RELAY can be used for
+both ath9k and ath10k hardware.
