From 7202e65b1eeeb54e0ec634c63d102b8cf670ea3b Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Oct 2023 11:43:28 +0800 Subject: crypto: cts - 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.
