+Subject: [PATCH] Linux 5.6: garbage collect CRYPTO_TFM_RES_BAD_KEY_LEN flag
+
+commit 674f368a952c48ede71784935a799a5205b92b6c "crypto: remove
+CRYPTO_TFM_RES_BAD_KEY_LEN" in Linux 5.6 removed the above flag since it wasn't
+enforced anywhere (and thus useless) and any external modules now using it end
+up FTBFS.
