It is no longer used in the i915 code, so isolate it from the shared struct. This was originally part of: commit 0e275518f325418d559c05327775bff894b237f7 Author: Ben Widawsky <ben@bwidawsk.net> Date: Mon Jan 14 13:35:33 2013 -0800 agp/intel: decouple more of the agp-i915 sharing Reviewed-by: Rodrigo Vivi <rodrigo.vivi@gmail.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> That commit had some other hunks which can't be used due to issues Daniel found in previous commits. Signed-off-by: Ben Widawsky <ben@bwidawsk.net> [danvet: drop squash notice from the commit since it's imo ok to keep this one separate.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
