No. > drivers/gpu/drm - no, because v4l2 wants to use it > drivers/media/video - no, because DRM drivers want to use it > drivers/video - no, because v4l2 and drm drivers want to use it I don't believe it exists currently, so it would need to be created. Perhaps adding a layer of directory to combine these. This patch alone is not enough to really justify that, but if there's a lot more shared code possible then it would be the right direction. > Maybe drivers/of-graph/ ?
