In that case the PTP controlling PF\n(adapter->ctrl_pf) is never initialized in the VM, so ice_get_ctrl_ptp()\nreturns NULL and triggers WARN_ON() in ice_ptp_setup_pf().\n\nSince this is an expected behavior in that configuration, replace\nWARN_ON() with an informational message and return -EOPNOTSUPP."
