The serial_table is used to map the minor number of the usb serial device
to its associated context. The table is updated in the probe method and
in hso_serial_ref_free() which is called either from the tty cleanup
method or from the usb disconnect method.
This patch ensures that the serial_table is updated in the disconnect
method and no more from the cleanup method to avoid the following
potential race condition.
- hso_disconnect() is called for usb interface "x". Because the serial
port was open and because the cleanup method of the tty_port hasn't
been called yet, hso_serial_ref_free() is not run.
- hso_probe() is called and fails for a new hso serial usb interface
"y". The function hso_free_interface() is called and iterates
over the element of serial_table to find the device associated to
the usb interface context.
If the usb interface context of usb interface "y" has been created
at the same place as for usb interface "x", then the cleanup
functions are called for usb interfaces "x" and "y" and
hso_serial_ref_free() is called for both interfaces.
- release_tty() is called for serial port linked to usb interface "x"
and possibly crash because the tty_port structure contained in the
hso_device structure has been freed.

The function hso_serial_common_free() is called either by the cleanup
method of the tty or by the usb disconnect method.
In the former case, the usb_disconnect() has been already called
and the sysfs group associated to the device has been removed.
By calling tty_unregister directly from the usb_disconnect() method,
we avoid a warning due to the removal of the sysfs group of the usb
device.

When the device disappear, the function hso_disconnect() is called to
perform cleanup. In the cleanup function, hso_free_interface() calls
tty_port_tty_hangup() in view of scheduling a work to hang up the tty if
needed. If the port was not open then hso_serial_ref_free() is called
directly to cleanup everything. Otherwise, hso_serial_ref_free() is called
when the last fd associated to the port is closed.
For each open port, tty_release() will call the close method,
hso_serial_close(), which drops the last kref and call
hso_serial_ref_free() which unregisters, destroys the tty port
and finally frees the structure in which the tty_port structure
is included. Later, in tty_release(), more precisely when release_tty()
is called, the tty_port previously freed is accessed to cancel
the tty buf workqueue and it leads to a crash.
In view of avoiding this crash, we add a cleanup method that is called
at the end of the hangup process and we drop the last kref in this
function when all the ports have been closed, when tty_port is no
more needed and when it is safe to free the structure containing the
tty_port structure.

drivers are built as dynamic modules. This patch addresses this issue
While at it, fix the Makefile and code to build both netcp_core and

This also requires exporting of API calls provided by netcp_core so that
