Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels
to prevent the N_TTY line discipline functions read_chan() and
n_tty_receive_buf() from running at the same time. 2.2.15 introduced
tty->read_lock to protect access to the N_TTY read buffer, which is the
only state requiring protection between these two functions.
The current TTY_DONT_FLIP implementation is broken for SMP, and is not
universally honored by drivers that send data directly to the line
discipline receive_buf function.
Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is
not universally honored, it is removed.

I've always found this flag confusing. Now that devfs is no longer around, it
has been renamed, and the documentation for when this flag should be used has
been updated.
Also fixes all drivers that use this flag.

Some usbserial functions returns -EINVAL if the port doesn't exist or if

If either the driver's open() method or try_module_get() fails, we need to
set 'tty->driver_data' and 'port->tty' to NULL in serial_open(), otherwise
we'll get an OOPS in usb_device_disconnect() when the device is disconnected.

Al Borchers suggested to do this in his review of my previous patch.
I guess that I skipped this initially because of my visceral dislike
of sizeof(data). But in this case it seems well localized.

While an Edgeport is allocating individual port structures, if kmalloc
returns NULL, the serial structure is freed and -ENOMEM, but the ports
allocated before the failure are not freed. This patch addresses that
condition.

By the way I have to ask you to add new (vid,pid) pair to cp2101 driver.
This device is argussoft's avr in-system programmer AS3M,
http://atmel.argussoft.ru/hard.htm
it's based on cp2101 chip and works pretty well with the linux driver.
It could be used with argussoft's `asisp1109.exe'

I introduced this way back in 2.6.13 when adding the port lock logic.
This device talks out through different "ports" all at the same time, so
the lock logic was wrong, preventing any data from ever being sent
properly.
Thanks a lot to Bernhard Reiter <bernhard@intevation.de> for being
patient and helping with debugging this.

If serial_open() fails at the port assignment or mutex_lock_interruptible()
is interrupted, the 'serial' object will never be freed.
We should call kref_put() when those errors happens.

If the device is disconnected while serial_open() is executing and
either try_module_get() or the device specific open function fails, the
kref_put() call in the 'bailout_kref_put' label will free the memory
pointed out by 'port'.
The subsequent dereferences in the 'bailout_kref_put' label will be
invalid.
The fix is just to assure kref_put() is called after any 'port' usage.
