You shouldn't need this pad test: it's done in the v4l2-subdev.c core code already. But please double-check :-)
oh right - forgot to check that. Yes, v4l2-subdev.c has pad bounds checking on all ops I use so I can remove them.
Can you post the output of the v4l2-compliance test? I'm curious to see it.
it's in the cover letter (should I move it to the driver patch for subsequent submittals?)
Can you also try to run v4l2-compliance -m /dev/mediaX? That also tests whether the right entity types are set (note: testing for that should also happen in the subdev compliance test, but I haven't done that yet).

Is something missing after v4l2_i2c_subdev_init() or is this perhaps something missing in the imx media drivers?
v4l2_i2c_subdev_init(sd, client, &tda1997x_subdev_ops); snprintf(sd->name, sizeof(sd->name), "%s %d-%04x", id->name, i2c_adapter_id(client->adapter), client->addr); sd->flags = V4L2_SUBDEV_FL_HAS_DEVNODE | V4L2_SUBDEV_FL_HAS_EVENTS; sd->entity.ops = &tda1997x_media_ops;
