Probably better written as:

	/* if reset finished and it's still not enabled -- handoff */
	if (!(port_status & PORT_PE))
		/* with integrated TT, there's nobody to hand it to! */
		fotg210_dbg(fotg210, "failed to enable port %d on root hub TT\n",
			    index + 1);
	else
		fotg210_dbg(fotg210, "port %d reset complete, port enabled\n",
			    index + 1);

	return port_status;
