Nobody should be using the generic usb-serial for anything other than
testing. Still, it's not a good thing that it's easy to lock up. There
is a traceback from NMI oopser here:
https://bugzilla.redhat.com/show_bug.cgi?id=431379
But in short, if a line discipline has a chance to echo anything, input
can loop back a write method. So, don't call tty_flip_buffer_push from
under a lock taken on write path.

Move the Onda H600/ZTE MF33 device from the sierra driver to the option
driver.
The reason it was moved is because the sierra driver is starting to support
more and more sierra proprietary features, so it makes more sense to keep
sierra only devices in there.

this driver uses usb_get_intfdata() == NULL as a test for disconnect().
You must not do that as this races with probe(). By the time you test
your erstwhile interface may already be somebody else's interface.

flag and use locking against disconnect() where required in close().

This fixes a problem where the mos7720 driver will make io to a device from

[PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors
There are more devices similar to the Olimex JTAG adaptor, in that the first
port of the FT2232C is used for JTAG, and only the second port is available as
UART.
I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and
added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the
OOCDlink device.
I've also updated the KERN_INFO message sent to userspace to remove the word
'olimex' and an extra '\n' that was causing an empty line in dmesg.

Without this fix, the pl2303 usb-serial adapter would not suspend properly
unless it had been opened first. A pl2303 type_1 chip will still break if the
system is hibernated while the RS-232 connector is powered by another system.
This was broken before, and a reset resume does not fix it. All other suspend
and autosuspend scenarios work with ATEN pl2303 adaptors with HX and type_1 chips.

Claim the interface for a USB to serial converter when the tty is open,
and release the interface when the tty is closed.
If a driver doesn't provide a resume function, use the generic resume
instead.
Make sure the generic resume function does not submit the URBs if we're
coming back from autosuspend. On autoresume, we know that the open
function will be called next, which will attempt to submit the URBs. If
we submit them in the resume function, the open will fail.
This works for:
- autosuspend
- suspending with the tty open or closed
- hibernate with the tty closed
A hibernate (or a suspend that causes the USB subsystem to lose power)
has issues. If you have the tty open when you hibernate, a new tty will
be created when the device re-enumerates during resume.

open() method
The usb serial method set_termios() is called for the first time from
open() method in order to set up the termios structure with the default
device's settings, ignoring the current settings. Once it's initialized,
the next set_termios() calls will update the device with the
tty->termios settings.
Currently USB serial console code calls the driver open() method without
a tty and after that will allocate a fake tty and termios so the command
line arguments can be applied to the device
(console=ttyUSB0,115200,...). This makes the driver overwrite the
termios with the default settings and not applying the command line
options.
This patch changes usb_console_setup() to allocate the fake tty and
termios before the open() method is called.
Tested successfully with a pl2303

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.
When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
tty = port->tty;
if (!tty)
return;
tty_wakeup(tty);
which causes (manually copied):
