Subject: [PATCH 5/8] nvmem: make nvmem_bus_type constant

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

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