   7 Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
   8  config symbol
   9
  10 At the moment, spectral scan support, and with it RELAY, is always enabled
  11 with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
  12 RELAY in ath10k, and it unconditionally reserves a relay channel.
  13
  14 Having debugfs support in ath10k is often useful even on very small
  15 embedded routers, where we'd rather like to avoid the code size and RAM
  16 usage of the relay support. While ath10k-based devices usually have more
  17 resources than ath9k-based ones, it makes sense to keep the configuration
  18 symmetric to ath9k, so the same base kernel without RELAY can be used for
  19 both ath9k and ath10k hardware.
