similar to the other patch, this won't work: &skt->cb_dev is only available
and set if the parent device is a PCI device; therefore, &skt->dev is the
only thing we can use.

An alternative approach would be to move this initialization code only after
we've set dev_name. Could you test whether this approach works for you,
please?

Thanks,
	Dominik
