I ported an old tty driver to the new tty_port_ helper functions. And
I'm trying to track down a couple of bugs in the new version of the
driver.
Are calls to the port's activate/shutdown methods serialized (either
globally or per-port)?

The activate and shutdown methods are serialized by the per port mutex.
