+==== Error messages ====
+For warning and error messages we have ath10k_warn() and ath10k_err().
+ath10k_warn() should be used when ath10k still continues to work, for example then some limit has been reached or an unknown event has been received. It's also rate limited.
+ath10k_err() should be used when a fatal error has been detected and ath10k will shut itself down, for example during driver initialisation or firmware recover fails. It is NOT rate limited.
+Examples:
+  ath10k_warn(ar, "failed to submit frame %d: %d\n", frame_index, ret);
+  ath10k_err(ar, "failed to wake up the device from sleep: %d\n", ret);
