From 2fb7e4dd35c52933b18ff127bf92d703c8e2e897 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 5 Jan 2024 13:51:21 +0100 Subject: PNP: make pnp_bus_type const Now that the driver core can properly handle constant struct bus_type, move the pnp_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
