What is this doing in videodev2.h? This belongs in v4l2-common.h! > Both the return pointer and the probe pointer can be const as well. > > I'll make a patch for this since I've forgotten to adjust several > videobuf_queue_*_init functions as well in my bkl patch :-( And when did that get merged ? We haven't reached any agreement on this API change. It's pretty useless in its current form and will just contribute to the V4L2 kernel API bloat. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
