Alan Stern f9c99bb8b3 USB: usb-serial: replace shutdown with disconnect, release 
This patch (as1254) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

This driver exists because the "normal" serial driver doesn't work too well
with GSM modems. Issues:
- data loss -- one single Receive URB is not nearly enough
- nonstandard flow (Option devices) control
- controlling the baud rate doesn't make sense
This driver is named "option" because the most common device it's
used for is a PC-Card (with an internal OHCI-USB interface, behind
which the GSM interface sits), made by Option Inc.
Some of the "one port" devices actually exhibit multiple USB instances
on the USB bus. This is not a bug, these ports are used for different
device features.
