[media] v4l: removal of old, obsolete ioctls
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: 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. Note that any application compiled with a videodev2.h from 2.6.7 or later will be using the correct ioctls.

-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.
