[PATCH] nvdimm: make nvdimm_bus_type const

From: Ricardo B. Marliere
Date: Sun Feb 04 2024 - 15:19:58 EST


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