+Subject: [PATCH] websockets.c: unbreak build without TLS
+
+Commit 7943072b1f3b (Fix use_identity_as_username not working on websockets
+clients) added code which unconditionally accesses mosq-ssl, breaking the
+build when TLS support is disabled.
+
+Fix it by guarding this logic inside #ifdef WITH_TLS.
