The right thing is to do add an attach_ret().

static int do_attach(drv)
{
	if (drv->attach_ret)
		return drv->attach_ret();
	drv->attach();
	return 0;
}

Then we convert one driver to use the new function pointer and see if
it simplifies the code.  If so we can transition the others as well.  If
not then we give up.
