Hi Allen

Although correct, if you look higher up the call chain, this appears
to be not so useful.

rlb_initialize() is only called by bond_alb_initialize(), and it
propagates the -1. That is only called by bond_open() with:

	if (bond_alb_initialize(bond, (BOND_MODE(bond) == BOND_MODE_ALB)))
		return -ENOMEM;

So you might want to also modify this code, to return the return
value, rather than use the hard coded ENOMEM.

Since you code is OK as far as it goes:
