Do you use a kind of assert in DPDK? The patch looks OK, however, I
would prefer something like

	assert_not_null(name);
	assert_not_null(pci_dev);

Usually, if some outer code is broken by mistake, the assert catches
such an issue. At the same time, it documents the code by telling
"this must never be NULL here". I agree, that returning -EINVAL for
this kind of check is incorrect.

Same for other changes...
