From 6e30a66433afee90e902ced95d7136e8f7edcc7e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:18:34 +0100 Subject: driver core: class: remove struct module owner out of struct class The module owner field for a struct class was never actually used, so remove it as it is not doing anything at all.
