+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.
