From 8be0c877fb3b671dac0cf56d1f1f9e65f9a9fb81 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 19 Dec 2023 16:43:05 +0100 Subject: thunderbolt: make tb_bus_type const Now that the driver core can properly handle constant struct bus_type, move the tb_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
