if_dwc.c beginning line 1611 in main:
if (bus_alloc_resources(dev, dwc_spec, sc->res)) {
device_printf(dev, "could not allocate resources\n");
return (ENXIO);
}
/* Read MAC before reset */
dwc_get_hwaddr(sc, macaddr);
/* Reset the PHY if needed */
if (dwc_reset(dev) != 0) {
device_printf(dev, "Can't reset the PHY\n");
return (ENXIO);
}
If the reset of the PHY fails then the resources are not released.
