From 629f1afc15ee8f34ec67bef0c33b9bccca7eeecc Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 2 Jan 2020 19:59:06 -0800 Subject: crypto: algapi - remove obsoleted instance creation helpers Remove lots of helper functions that were previously used for instantiating crypto templates, but are now unused: - crypto_get_attr_alg() and similar functions looked up an inner algorithm directly from a template parameter. These were replaced with getting the algorithm's name, then calling crypto_grab_*(). - crypto_init_spawn2() and similar functions initialized a spawn, given an algorithm. Similarly, these were replaced with crypto_grab_*(). - crypto_alloc_instance() and similar functions allocated an instance with a single spawn, given the inner algorithm. These aren't useful anymore since crypto_grab_*() need the instance allocated first.
