The v4l2-ioctl core now only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(g|s)_parm. The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() it will now allow VIDEO_OVERLAY buffers as well. This should be fine as the fields the driver fills in, readbuffers and frame rate, aren't wrong for VIDEO_OVERLAY buffers.
