Often, usb drivers need some driver_info to get a device to work. To
have access to driver_info when using new_id, allow to pass a reference
vendor:product tuple from which new_id will inherit driver_info.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a

Genuine FTDI chips support only CS7/8. A previous fix in commit
8704211f65 ("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.

Make sure the TIOCMIWAIT mask is always honoured.
The CH341 interrupt status has a multiple-status changed flag which
indicates that multiple status changes has occurred since last interrupt
event. Unfortunately, if the final status is the same, there appears to
be no way to determine which signal(s) has changed (an even number of
times).
This means that the multiple-status flag should not be used in
TIOCMIWAIT as it leads to the signal mask argument being ignored (e.g.
TIOCMIWAIT could return if DSR changes twice, even though the user only
cares about carrier changes).

Add a driver which supports the following Moxa USB to serial converters:
* 2 ports : UPort 1250, UPort 1250I
* 4 ports : UPort 1410, UPort 1450, UPort 1450I
* 8 ports : UPort 1610-8, UPort 1650-8
* 16 ports : UPort 1610-16, UPort 1650-16
The UPORT devices don't directly fit the USB serial model. USB serial
assumes a bulk in/out endpoint pair per serial port. Thus a dual port
USB serial device is expected to have two bulk in/out pairs. The Moxa
UPORT only has one pair for data transfer and places a header on each
transfer over the endpoint indicating for which port the transfer
relates to. There is a second endpoint pair for events, such as modem
control lines changing state, setting baud rates etc. Again, a
multiplexing header is used on these endpoints.
Some ports need to have a kfifo explicitly allocated since the
framework does not allocate one if there is no associated endpoints.
The framework will however free it on unload of the module.
All data transfers are made on port0, yet the locks are taken on PortN.
urb->context points to PortN, even though the URB is for port0.
Where possible, code from the generic driver is called. However
mxuport_process_read_urb_data() is mostly a cut/paste of
usb_serial_generic_process_read_urb().
The driver will attempt to load firmware from userspace and compare
the available version and the running version. If the available
version is newer, it will be download into RAM of the device and
started. This is optional and the driver appears to work O.K. with
older firmware in the devices ROM.
This driver is based on the MOXA driver and retains MOXAs copyright.

Use direct baud-rate encoding rather than divisors for supported baud
rates.
This restores the way baud rates were set prior to commit 8d48fdf689
("USB: PL2303: correctly handle baudrates above 115200") which added
divisor encoding, but also switched to the new encoding method for all
baudrates above 115200.
As noted by Frank Schäfer <fschaefer.oss@googlemail.com>, baud rate 500k
was later errounously added to the supported baud-rate table although
it can only be set using divisors.
Note that the current implementation could easily be extended to support
arbitrary non-standard baud rates using divisors (e.g. by falling back
to divisors when the table lookup fails).
