[PATCH 3/4] serial: Allow port type to specify bugs that are not probed for.

[David Daney <ddaney@xxxxxxxxxxxxxxxxxx>]

Allow port type to specify bugs that are not probed for.

Add a bugs field to the serial8250_config and propagate it to the
port's bugs field when the port is registered and configured.
