+Subject: crypto: rng - Ensure set_ent is always present
+
+From: Herbert Xu <herbert@gondor.apana.org.au>
+
+commit c0d36727bf39bb16ef0a67ed608e279535ebf0da upstream.
+
+Ensure that set_ent is always set since only drbg provides it.
+
+Fixes: 77ebdabe8de7 ("crypto: af_alg - add extra parameters for DRBG interface")
