2016-03-07drm: etnaviv: clean up vram_mapping submission/retire pathRussell King
Currently, we scan the list of mappings each time we want to operate on the vram_mapping struct. Rather than repeatedly scanning these, look them up once in the submission path, and then use _reference and _unreference methods as necessary to manage this object.
