Also it may be unclear for the user from a specific PCI device ID of an affected PCI UART device which dedicated driver has to be configured in to handle it, so make the blacklist entries include that information to be printed if a device is encountered that cannot be handled because its dedicated driver has been excluded from configuration while the common driver refuses to handle it. See the respective change descriptions for further details. Please apply. Maciej
