[PATCH 3/4] serial: Allow port type to specify bugs that are notprobed for.

From: David Daney
Date: Tue Oct 07 2008 - 19:57:35 EST


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.
