From e869b72b33731063b50433eb6146d51a479995a1 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 09:40:50 -0300 Subject: greybus: 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 greybus_hd_type, greybus_module_type, greybus_interface_type, greybus_control_type, greybus_bundle_type and greybus_svc_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.
