This reverts commit 6a1a82df91.
RTS and DTR should not be modified based on CRTSCTS when calling
set_termios.
Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.
This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).
Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.

Call set_mctrl() and clear_mctrl() according to the flow control mode
selected. This makes serial communication for FT232 connected devices
work when CRTSCTS is not set.
This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

Remove multi-urb write from the generic driver and simplify the
prepare_write_buffer prototype:
int (*prepare_write_buffer)(struct usb_serial_port *port,
void *dest, size_t size);
The default implementation simply fills dest with data from port write
fifo but drivers can override it if they need to process the outgoing
data (e.g. add headers).

significantly for small writes while retaining maximum throughput.

device). This may be desirable for instance on an embedded system where

Remove superfluous error checks in completion handler:
- No need to check private data and urb pointers as we check urb-status
before dereferencing priv (which is not freed until urb has been killed
on close).
- No need to check tty as it is checked again when processing.
- No need to check urb->number_of_packets on bulk urb.
Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).

It enhances the driver for FTDI-based USB serial adapters to recognize and
support Northern Digital Inc (NDI) measurement equipment. NDI has been
providing this patch for various kernel flavors for several years and we would
like to see these changes built in to the driver so that our equipement works
without the need for customers to patch the kernel themselves.
The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c
and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things:
1. Define the VID and PIDs to allow the driver to recognize the NDI devices.
2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb
We would have chosen to map 38400 to the higher rate, similar to what
several other vendors have done, but some of our legacy customers actually
use 38400, therefore we remap 19200 to the higher rate.
3. We set the default transmit latency in the FTDI chip to 1ms for our devices.
Our devices are typically polled at 60Hz and the default ftdi latency
seriously affects turn-around time and results in missed data frames. We
have created a modprobe option that allows this setting to be increased.
This has proven necessary particularly in some virtualized environments.

The problem is that the usb-serial core was calling shutdown during

oops when the close method tried to use memory that had been

Added a function to set the packet size to be used based on the value from the
device endpoint descriptor. The FT2232H and FT4232H hi-speed devices will have
wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will
use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a
USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes,
except some FT232R and FT245R devices which customers have mistakenly
programmed to have wMaxPacketSize of 0 - this is an error and will be
overridden to use wMaxPacketSize of 64 bytes. The packet size used is
important as it determines where the driver removes the status bytes from the
incoming data. If it is incorrect, it will lead to data corruption.

Commit c45d6320 ("fix reference counting of ftdi_private") stopped
ftdi_sio_port_remove() from directly freeing the port-private data, with
the intention if the port was still open, it would be freed when
ftdi_close() is eventually called and releases the last refcount on the
structure.
That's all very well, but ftdi_sio_port_remove() still contains a call
to usb_set_serial_port_data(port, NULL) -- so by the time we get to
ftdi_close() for the port which was unplugged, it _still_ oopses on
dereferencing that NULL pointer, as it did before (and does in 2.6.29).
The fix is just not to clear the private data in ftdi_sio_port_remove().
Then the refcount is properly reduced to zero when the final kref_put()
happens in ftdi_close().
Remove a bogus comment too, while we're at it. And stop doing things
inside "if (priv)" -- it must _always_ be there.
Based loosely on an earlier patch by Daniel Mack, and suggestions by
Alan Stern.

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
