If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Herbert Xu commit f1d84af1835846a5a2b827382c5848faf2bb0e75 upstream. This patch removes the custom release parent function as the generic af_alg_release_parent now works for nokey sockets too.
