My own opinion is that a whitelist to enroll devices as they are tested is the safer approach, for the reason that getting test coverage on many of the older devices would be difficult. For example, I see id's of HP devices in the code that are probably 20 years old, and I doubt whether there are operational examples inside HPE today. That said, I can offer to test that a new patch to 8250_pci.c works on the device I recently added. Please cc me directly if that is helpful, as I don't always read the mailing lists such as linux-serial promptly. -- Randy Wright - Hewlett Packard Enterprise - rwright@xxxxxxx
