All dmx ioctls are compatible, and they are only implemented in one file, so we can replace the list of commands in fs/compat_ioctl.c with a single line in dmxdev.

The VIDEO_STILLPICTURE is only implemented by one driver, while VIDEO_GET_EVENT has two users in tree. In both cases, it is fairly easy to handle the compat ioctls in the native handler rather than relying on translation in fs/compat_ioctls.

In effect, this means that now the drivers implement both structure layouts in both native and compat mode, but I don't see anything wrong with that.
