* [PATCH] cdx: make cdx_bus_type constant

From: Kunwu Chan <chentao@kylinos.cn>

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 cdx_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.

* [PATCH] cdx: make cdx_bus_type constant

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