Subject: crypto: algif_skcipher - Remove custom release parent function
From: Herbert Xu <herbert@gondor.apana.org.au>
commit d7b65aee1e7b4c87922b0232eaba56a8a143a4a0 upstream.
This patch removes the custom release parent function as the
generic af_alg_release_parent now works for nokey sockets too.
