From 869eb452aed66ac74c0ee7ecd6f9d545b975c676 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Thu, 8 Feb 2024 16:17:51 -0300 Subject: [PATCH] staging: vc04_services: vchiq_arm: make vchiq_bus_type const Now that the driver core can properly handle constant struct bus_type, move the vchiq_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
