dma-buf: make kobj_type structure constant

t-8ch · danvet · commit fb073aa27a7e · 2023-02-17T09:16:34.000+01:00
Since commit ee6d3dd ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.
