[PATCH 1/1] mcb: make mcb_bus_type const

From: Johannes Thumshirn
Date: Tue Feb 27 2024 - 06:41:04 EST


From: "Ricardo B. Marliere" <ricardo@xxxxxxxxxxxx>

Now that the driver core can properly handle constant struct bus_type,
move the mcb_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
