From 9d11b13402d1b80f7f3ca5061d75f15cf8002555 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 13 Mar 2023 19:29:18 +0100 Subject: USB: mark all struct bus_type as const Now that the driver core can properly handle constant struct bus_type, move all of the USB subsystem struct bus_type structures as const, placing them into read-only memory which can not be modified at runtime.
