From 8ab0f4605d5ce3c0d386b3828b07719f1e8e0505 Mon Sep 17 00:00:00 2001 From: Kunwu Chan Date: Fri, 23 Aug 2024 14:24:40 +0800 Subject: bus: fsl-mc: make fsl_mc_bus_type const Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the fsl_mc_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
