[PATCH 0/5] USB: serial: handle unbound ports

[Johan Hovold <johan@kernel.org>]

Drivers must make sure that a port is bound to a driver before accessing
port data in non-port callbacks.

Note that this is needed even with the port-driver bind attributes
removed as an individual port may have failed to probe.
