From f36be9ce8146faabdbbf74ee0499edb2039c53a5 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 19 Dec 2023 14:13:10 +0100 Subject: EDAC: constantify the struct bus_type usage In many places in the edac code, struct bus_type pointers are passed around and then eventually sent to the driver core, which can handle a constant pointer. So constantify all of the edac usage of these as well because the data in them is never modified by the edac code either.
