Subject: [PATCH] nvdimm: make nvdimm_bus_type const
Date: Sun, 04 Feb 2024 17:20:07 -0300 [thread overview]
Message-ID: <20240204-bus_cleanup-nvdimm-v1-1-77ae19fa3e3b@marliere.net> (raw)
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.
