From 973fb3fb50e3959d90179d09ed3ce454dd7bc6e4 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 21 Jan 2016 17:10:56 +0800 Subject: crypto: skcipher - Add default key size helper While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given. Rather than having it poke into the guts of the algorithm to get max_keysize, let's provide a helper that is meant to give a sane default (just in case we ever get an algorithm that has no maximum key size).
