Add the missing check. I think this check could go in the v4l2 core too. It already does a similar check for QUERYBUF, QBUF, DQBUF, etc. If the driver doesn't provide a method for ->vidioc_try_fmt_foo() then the v4l2 core will reject a call with .type == V4L2_BUF_TYPE_foo. It seems like it should be ok to do this for S_PARM and G_PARM too. -- 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
