The name of the dummy device should be filled in as well. How about
something like this:

--- a/drivers/net/wireless/ath/ath10k/core.c
+++ b/drivers/net/wireless/ath/ath10k/core.c
@@ -3576,6 +3576,9 @@ struct ath10k *ath10k_core_create(size_t priv_size, struct device *dev,
  		  ath10k_core_set_coverage_class_work);
  
  	init_dummy_netdev(&ar->napi_dev);
+	snprintf(ar->napi_dev.name, sizeof(ar->napi_dev.name), "%s",
+		 wiphy_name(ar->hw->wiphy));
+	ar->napi_dev.threaded = 1;
  
  	ret = ath10k_coredump_create(ar);
  	if (ret)
