This patch (as1292) modifies the USB serial console driver, to make it

Prevent the serial device from being autosuspended.

This patch (as1287) makes serial_install() be reponsible for acquiring
references to the usb_serial structure and the driver module when a

it, because a tty can be opened many times whereas it is installed
only once, when it is created. (Not to mention that these actions are
reversed when the tty is released, not when it is closed.) Finally,
it is at install time that the TTY core takes its own reference to the
usb_serial module, so it is only fitting that we should act the same
way in regard to the lower-level serial driver.

usb-serial: change logic of serial lookups
This patch (as1286) changes usb_serial_get_by_index(). Now the
routine will check whether the serial device has been disconnected; if
it has then the return value will be NULL. If the device hasn't been
disconnected then the routine will return with serial->disc_mutex
held, so that the caller can use the structure without fear of racing
against driver unloads.
This permits the scope of table_mutex in destroy_serial() to be
reduced. Instead of protecting the entire function, it suffices to
protect the part that actually uses serial_table[], i.e., the call to
return_serial(). There's no longer any danger of the refcount being
incremented after it reaches 0 (which was the reason for having the
large scope previously), because it can't reach 0 until the serial
device has been disconnected.
Also, the patch makes serial_install() check that serial is non-NULL
before attempting to use it.

usb-serial: change referencing of port and serial structures
This patch (as1284) changes the referencing of the usb_serial and
usb_serial_port structures in usb-serial.c. It's not feasible to make
the port structures keep a reference to the serial structure, because
the ports need to remain in existence when serial is released -- quite
a few of the drivers expect this. Consequently taking a reference
to the port when the device file is open is insufficient; such a
reference would not pin serial.
To fix this, we now take a reference to serial when the device file is
opened. The final put_device() for the ports occurs in
destroy_serial(), so that the ports will last as long as they are
needed.
The patch initializes all the port devices, including those in the
unused "fake" ports. This makes the code more uniform because they
can all be released in the same way. The error handling code in
usb_serial_probe() is much simplified by this approach; instead of
freeing everything by hand we can use a single usb_serial_put() call.
Also simplified is the port-release mechanism. Instead of being two
separate routines, port_release() and port_free() can be combined into
one.

serial: move the flags into the tty_port field
Fortunately the serial layer was designed to use the same flag values but
with different names. It has its own SUSPENDED flag which is a free slot in
the ASYNC flags so we allocate it in the ASYNC flags instead.

This is needed and requested in various forms for ConsoleKit, screenblank

FIXME: Should this be a waitactive ioctl or a new device file you can poll
and read events from. We need the code anyway to fix up the existing broken
wait for console switch logic but the ConsoleKit people would prefer the
new device to the ioctl we have here

tty: USB hangup is racy
The USB layer uses tty_hangup to deal with unplugs of the physical hardware
(analogous to loss of carrier) and then frees the resources. However the
tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup
which is the non async version to avoid freeing resources too early.
