95da310e66 usb_serial: API all change
USB serial likes to use port->tty back pointers for the real work it does and
to do so without any actual locking. Unfortunately when you consider hangup
events, hangup/parallel reopen or even worse hangup followed by parallel close
events the tty->port and port->tty pointers are not guaranteed to be the same
as port->tty is the active tty while tty->port is the port the tty may or
may not still be attached to.

So rework the entire API to pass the tty struct. For console cases we need
to pass both for now. This shows up multiple drivers that immediately crash
with USB console some of which have been fixed in the process.

Longer term we need a proper tty as console abstraction

71be4f81e9 USB: debug port converter does not accept more than 8 byte packets
USB debug port only supports 8 byte rx/tx packets. Although spec implies that
"if a packet larger than eight bytes is received from the remote computer, the
device must break the larger packet into eight-byte packets before sending the
data to the Debug Port", the real PLX NET20DC device does not handle it right -
data is corrupted on debug port end if serial interface sends >8 byte urbs.
Patch below fixes the issue by limiting tx urb to 8 byte.

62ad296b6c USB: fix usb serial pm counter decrement for disconnected interfaces
usb serial decrements the pm counter even if an interface has been

already to another driver. This patch introduces a check for disconnected

b2bdd1f504 USB: cp2101.c fix sparse signedness mismatch warnings
The get/set 2101_config helpers take an unsigned int rather than an
int.  It is safe to change these in each case and may even produce
better code as it will be an unsigned divide rather than a signed
divide in places.  All other manipulation was setting/masking bits
which will not be affected by the sign change.

Fixes the following sparse warnings:

2542335ccf USB: New device ID for ftdi_sio driver
Here's a new device ID for the ftdio_sio driver.
The diff is with linus's tree as of this morning.

The device is the RigExpert Tiny USB Soundcard Transceiver Interface for ham

(I didn't actually test this. A fellow ham couldn't get the device to work, and
I suggested binding the device ID using sysfs - see
"http://jk.ufisa.uninett.no/usb/". However, he had had moved on to other things
by then. I guess adding the device ID to the kernel "on spec" won't hurt.
The relevant part of cat /proc/bus/usb/devices shows:

cdafc37a7b USB: do not handle device 1410:5010 in 'option' driver
This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:

lsusb -v -d 1410:5010 | grep InterfaceClass
      bInterfaceClass         8 Mass Storage

After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:

% lsusb -v -d 1410:4400 | grep InterfaceClass
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceClass       255 Vendor Specific Class

Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.

8594303a7a fix irq flags for iuu_phoenix.c
The file drivers/usb/serial/iuu_phoenix.c uses "int" for flags.  This can
cause hard to find bugs on some architectures.  This patch converts the flags
to use "long" instead.

This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

21ae1dd1d4 USB: airprime: unlock mutex instead of trying to lock it again
The following patch fixes a [probable] copy & paste mistake in
airprime.c. Instead of unlocking an acquired mutex, the actual
code tries to lock it again.

f34d7a5b70 tty: The big operations rework
- Operations are now a shared const function block as with most other Linux
  objects

- Introduce wrappers for some optional functions to get consistent behaviour

- Wrap put_char which used to be patched by the tty layer

- Document which functions are needed/optional

- Make put_char report success/fail

- Cache the driver->ops pointer in the tty as tty->ops

- Remove various surplus lock calls we no longer need

- Remove proc_write method as noted by Alexey Dobriyan

- Introduce some missing sanity checks where certain driver/ldisc
  combinations would oops as they didn't check needed methods were present

a5b6f60c5a usb serial: more fixes and groundwork for tty changes
- If a termios change fails due to lack of memory we should copy the
   old settings back over as the device has not changed
 - Note various locking problems
 - kl5kusb105 had various remaining tty flag handling problems
 - Make safe_serial use tty_insert_flip_string not open coded loops
 - set termios speed properly in usb_serial
