Subject: 8250: allow port type to specify bugs that are not probed for
From: David Daney <ddaney@xxxxxxxxxxxxxxxxxx>
Add a bugs field to the serial8250_config and propagate it to the port's
bugs field when the port is registered and configured.
This is a follow on to the previous patch. Now that we can specify the
port type and don't have to probe for it, we can avoid probing for bugs if
they are known with certainty to exist.
The alternative is to load up 8250.c with a bunch of OCTEON specific
special cases in the probing code.
