From bf028cfe8a505b5330be7df628ac19ffad48f932 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Oct 2023 11:43:32 +0800 Subject: crypto: xts - 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.
