From b8a730836c6b1788ca2fbd6bcc2ac99e97ef7de9 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 09:45:50 -0300 Subject: thunderbolt: Constify the struct device_type usage Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the tb_domain_type, tb_retimer_type, tb_switch_type, usb4_port_device_type, tb_service_type and tb_xdomain_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.
