    Which is a different behaviour, now you can't create a device node
    manually anymor. Also note that the feature you rely on here (devfs
    presetting file->private_data) will go away in the next round of patches,
    see Al Viro's patchit for a generic replacement that works with or
    without devfs.

    Okay, you're right I should have read more of the code to get the global
    picture. You still wan't an owner field for at least struct dvb_device
    device, though - but the try_module_get must go into dvb_generic_open
    and maybe in more other places where you use the "backend" modules.
