3.2.77-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>
commit f1d84af1835846a5a2b827382c5848faf2bb0e75 upstream.
This patch removes the custom release parent function as the
generic af_alg_release_parent now works for nokey sockets too.
