Yes. MODULE_VERSION has nothing to do with the warning that you are
getting. That warning is coming from your device registration. You
need to have something like:
static struct cdevsw lpt_cdevsw = {
.d_version = D_VERSION,
.d_flags = D_NEEDGIANT,
}
in it.
MODULE_VERSION is the version of the entire module, for external
linking to that module.
