Yes, it is there already:
#ifdef CONFIG_VIDEO_V4L1_COMPAT
/********************************************************
All other V4L1 calls are handled by v4l1_compat module.
Those calls will be translated into V4L2 calls, and
__video_do_ioctl will be called again, with one or more
V4L2 ioctls.
********************************************************/
if (_IOC_TYPE(cmd) == 'v' && cmd != VIDIOCGMBUF &&
_IOC_NR(cmd) < BASE_VIDIOCPRIVATE) {
return v4l_compat_translate_ioctl(file, cmd, arg,
__video_do_ioctl);
}
#endif
and now I don't understand why the V4L1 'v' cmds of Skype are not working
correctly; will add some printf's...
