From 37d158d0b05144f696323ae5bbfe1e137f7c06d3 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 20 Dec 2023 08:38:46 +0100 Subject: HID: make hid_bus_type const Now that the driver core can properly handle constant struct bus_type, move the hid_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
