From 00b9850e7307ff690639dd0584a50dd8a72d3548 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 5 Jan 2024 11:16:17 +0100 Subject: [PATCH] greybus: make greybus_bus_type const Now that the driver core can properly handle constant struct bus_type, move the greybus_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
