It would be a good idea for someone to audit all the serial drivers.
The basic idea is simple:
The .port_probe and .port_remove methods should handle
anything connected with an individual port.
The .probe, .attach, .disconnect, and .release methods
should handle things associated with the entire device,
not with any particular port. They definitely should
not call usb_get_serial_port_data().
It wouldn't be surprising to find that several of the drivers violate
these rules.
