0ec8648379 USB: Add support for Mobilcom Debitel USB UMTS Surf-Stick to option driver
This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf
stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...).

To see these ids, you need to switch the stick to modem operation first
with the help of usb_modeswitch. This makes it switch from 1c9e:f000 to
1c9e:9603 and thus be recognized by the option driver.

0de6ab8b91 USB: ftdi_sio: Keep going when write errors are encountered.
The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write.  On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.

If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.

Add D-Link DWM-162-U5 device id 1e0e:ce16 into option driver. The device
has 4 interfaces, of which 1 is handled by storage and the other 3 by
option driver.

The device appears first as CD-only 05c6:2100 device and must be
switched to 1e0e:ce16 mode either by using "eject CD" or usb_modeswitch.

d94c7bd4c1 tty: cp210x: Fix carrier handling
Original discussion:
http://thread.gmane.org/gmane.linux.usb.general/23217/focus=23248
or
http://marc.info/?l=linux-usb&m=125553790714133&w=2

9a68e39d4a broke carrier handling so that a
cp210x setup which needed the carrier lines set up (non CLOCAL) which did
not make a call which set the termios bits left the lines down even if
CLOCAL was not asserted.

Fix this not by reverting but by adding the proper dtr_rts and
carrier_raised methods. This both sets the modem lines properly and also
implements the correct blocking semantics for the port as required by
POSIX.

b64dc0a597 USB: serial: sierra driver autopm fixes
This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in  functions sierra_open(), sierra_close() and
stop_read_write_urbs().

The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.

The bug fix  in sierra_open() function restores the autopm interface
state on error condition.

The bug fix in in stop_read_write_urbs() function assures that both
receive and interrupt urbs are recycled.

If certain kinds of errors occur during probing, the core may call a

(possibly from work queue which also is cancelled on close).

f278a2f7bb tty: Fix regressions caused by commit b50989dc
The following commit made console open fails while booting:

	commit b50989dc44
	Author: Alan Cox <alan@linux.intel.com>
	Date:   Sat Sep 19 13:13:22 2009 -0700

	tty: make the kref destructor occur asynchronously

Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:

INIT open /dev/console Input/output error

It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229

The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.

Fix it as per the following Alan's suggestion:

  Fun but it's actually not a bug and the fix is wrong in itself as
  the port may be closing but not yet being destructed, in which case
  it seems to do the wrong thing.  Opening a tty that is closing (and
  could be closing for long periods) is supposed to return -EIO.

  I suspect a better way to deal with this and keep the old console
  timing is to split tty->shutdown into two functions.

  tty->shutdown() - called synchronously just before we dump the tty
  onto the waitqueue for destruction

  tty->cleanup() - called when the destructor runs.

  We would then do the shutdown part which can occur in IRQ context
  fine, before queueing the rest of the release (from tty->magic = 0
  ...  the end) to occur asynchronously

  The USB update in -next would then need a call like

       if (tty->cleanup)
               tty->cleanup(tty);

  at the top of the async function and the USB shutdown to be split
  between shutdown and cleanup as the USB resource cleanup and final
  tidy cannot occur synchronously as it needs to sleep.

  In other words the logic becomes

       final kref put
               make object unfindable

       async
               clean it up

25b8286805 USB-serial: pl2303: fix baud rate handling in case of unsupported values
According to the datasheets, the PL2303 supports a set of 25 baudrates.
The baudrate is set as a 4 byte value directly.

During my experiments with device 067b:2303 (PL2303X), I noticed that
 - the bridge-controller always uses 9600 baud if invalid/unsupported baud rate
   values are set
 - the baud rate value returned by usb_control_msg(..., GET_LINE_REQUEST, ...)
   does not reflect the actually used baudrate. Always the last set value is
   returned, even if it was invalid and not used by the controller.

This patch fixes the following issues with the current code:
1.) make sure that only supported baudrates are set (are there any buggy
    chip revisions out there which don't "like" other values... ?).
2.) always set the baudrate to the next nearest supported baudrate.
3.) applications can now read back the resulting baudrate properly, because
    tty_encode_baud_rate(...) is now fed with the actually used baudrate.

8e8dce0650 USB: use kfifo to buffer usb-generic serial writes
When do_output_char() attempts to write a carriage return/line feed sequence,
it first checks to see how much buffer room is available. If there are at least
two characters free, it will write the carriage return/line feed with two calls
to tty_put_char(). It calls the tty_operation functions write() for devices that
don't support the tty_operations function put_char(). If the USB generic serial
device's write URB is not in use, it will return the buffer size when asked how
much room is available. The write() of the carriage return will cause it to mark
the write URB busy, so the subsequent write() of the line feed will be ignored.

This patch uses the kfifo infrastructure to implement a write FIFO that
accurately returns the amount of space available in the buffer.

5128a66c66 USB: ark3116: add IrDA support for Gembird UIR-22
Add IrDA support to ark3116 driver.  This makes Gembird UIR-22 USB to IrDA
adapter work (vendor ID 0x18ec, device ID 0x3118).  This adapter contains
ARK3116T USB serial chip and an IrDA transceiver, thus a command like
"irattach /dev/ttyUSB0 -s" is needed.

All magic numbers were captured using usbsnoop from windows driver that
came with the device.

81e5b23cd2 USB: fix wrong order of events in usb serial suspension
if a subdriver has an additional suspend method, it must be called
first to allow the subdriver to return -EBUSY, because the second
half cannot be easily undone.
