From d15232fe37de805bd155e9b150d7aaf86feb5d3b Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Oct 2023 11:43:30 +0800 Subject: crypto: hctr2 - 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.
