There's no need to print the number of endpoints per interface or
endpoint wMaxPacketSize during port probe. This information is readily
available using lsusb should it ever be needed.

Note that this also fixes the wMaxPacketSize being incorrectly reported
on big-endian systems due to a missing le16_to_cpu().

Fix NULL-pointer dereference when probing an interface with no
endpoints.

These devices have two bulk endpoints per interface, but this avoids
crashing the kernel if a user forces a non-FTDI device to be probed.

Note that the iterator variable was made unsigned in order to avoid
a maybe-uninitialized compiler warning for ep_desc after the loop.

Genuine FTDI chips support only CS7/8. A previous fix in commit
8704211f ("USB: ftdi_sio: fixed handling of unsupported CSIZE
setting") enforced this limitation and reported it back to userspace.

However, certain types of smartcard readers depend on specific
driver behaviour that requests 0 data bits (not 5) to change into a
different operating mode if CS5 has been set.

This patch reenables this behaviour for all FTDI devices.

Tagged to be added to stable, because it affects a lot of users of
embedded systems which rely on these readers to work properly.

FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would
only report this limitation for CS6 to dmesg and fail to reflect this fact to
tcgetattr.

This patch reverts the unsupported CSIZE setting and reports the fact with less
severance to dmesg for both CS5 and CS6.

To test the patch it's sufficient to call

    stty -F /dev/ttyUSB0 cs5

which will succeed without the patch and report an error with the patch
applied.

As an additional fix this patch ensures that the control request will always
include a data bit size.

This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 6f602912 ("usb:

breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak

Remove the port data refcounting and release the private data
explicitly at port remove.

The port data refcounting was used to make sure the port data was not
freed until the last tty reference was closed. Since moving over to tty
ports, the underlying assumptions are no longer valid as close is now
called as part of tty port shutdown, which can occur before the final
tty reference is dropped on device disconnect.

This means that the private port data refcounting is now completely
useless, as the last reference will always be dropped on port_remove.
