It's completely unused and there's really no reason for this:
- drm_framebuffer structures are invariant after creation, no need for
helpers to manipulate them.
- drm_framebuffer structures should just be embedded (and that's what
all the drivers do).
Stumbled over this since some folks are apparently concerned with the
overhead of struct drm_framebuffer and this is an easy 8 byte saving.
More could be gained by ditching the legacy fields and recomputing
stuff from the fourcc value. But that would require some drm-wide
cocci and real justification.
