Since many years I use struct v4l2_ext_controls and VIDIOC_S_EXT_CTRLS for
setting both User Controls and MPEG Controls. This works with ivtv and
pvrusb2.
Now I discovered that saa7134-empress returns "Invalid argument" if I do this.
I have to use struct v4l2_control ctrl and VIDIOC_S_EXT_CTRLS. And this works
also with ivtv.
Is this the right method for all V4L2_CTRL_CLASS_USER control IDs?
Or is it a bug of the saa7134 driver that it doesn't work with
VIDIOC_S_EXT_CTRLS ?
