From d25635bc95e25386e70ccd071fb74c867642db23 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Oct 2023 11:43:24 +0800 Subject: crypto: authencesn - Only access common skcipher fields on spawn As skcipher spawns may be of the type lskcipher, only the common fields may be accessed. This was already the case but use the correct helpers to make this more obvious.
