If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Herbert Xu commit d7b65aee1e7b4c87922b0232eaba56a8a143a4a0 upstream. This patch removes the custom release parent function as the generic af_alg_release_parent now works for nokey sockets too.
