No, as I've explained repeatedly elsewhere, it does not cause any
resource leaks. [1][2]

The autosuspend setting leaks if you will, but that only matters in the
theoretical corner case of someone rebinding a different driver (which
will soon also taint the kernel).

So don't exaggerate the impact, this is essentially just a cleanup,
which is fine in itself.
