From 37c6fc323a81a14612626a1eec64f4690d89f234 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 21 Dec 2023 10:42:57 +0800 Subject: crypto: skcipher - Pass statesize for simple lskcipher instances When ecb is used to wrap an lskcipher, the statesize isn't set correctly. Fix this by making the simple instance creator set the statesize.
