What: Video4Linux: Remove obsolete ioctl's
When: kernel 2.6.39
Files: include/media/videodev2.h
Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
#define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
#define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
#define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
#define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
#define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
#define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.
