5e71fc8629 USB: keyspan_pda: add new device id
Add USB VID/PID for Xircom PGMFHUB USB/serial component.  (The hub and SCSI
bridge on that hardware are recognized out of the box by existing drivers.)
Tested VID/PID using new_id and loopback connection and was met with
success, but that's all the testing done.

c7d373c3f0 usb: ftdi_sio: Add jtag quirk support for Cyber Cortex AV boards
This patch integrates Cyber Cortex AV boards with the existing
ftdi_jtag_quirk in order to use serial port 0 with JTAG which is
required by the manufacturers' software.

Steps: 2

[ftdi_sio_ids.h]
1. Defined the device PID

[ftdi_sio.c]
2. Added a macro declaration to the ids array, in order to enable the
jtag quirk for the device.

aa91def41a USB: ch341: set tty baud speed according to tty struct
The ch341_set_baudrate() function initialize the device baud speed
according to the value on priv->baud_rate. By default the ch341_open() set
it to a hardcoded value (DEFAULT_BAUD_RATE 9600). Unfortunately, the
tty_struct is not initialized with the same default value. (usually 56700)

This means that the tty_struct and the device baud rate generator are not
synchronized after opening the port.

Fixup is done by calling ch341_set_termios() if tty exist.
Remove unnecessary variable priv->baud_rate setup as it's already done by
ch341_port_probe().
Remove unnecessary call to ch341_set_{handshake,baudrate}() in
ch341_open() as there already called in ch341_configure() and
ch341_set_termios()

There is old, unused code that is #defined out by the use of NOTMOS7840
and NOTMCS7840 - these are not defined anywhere.

If NOTMOS7840 is defined then the code will break on null pointer

broken anyway, so why not just remove it.

using the device it may spam the logs with -EPROTO (71) messages as it

Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output
these messages for debugging.  The generic driver treats these as
errors.

to make unsolicited response codes work correctly. Move these devices from
the qcserial driver where they have been added by commit
70a3615fc0 ("usb: qcserial: add Sierra Wireless

to ensure that
1. the sendsetup code is not used for the DIAG/DM and NMEA interfaces
2. the option driver does not attach to the QMI/network interfaces

The "status" is uninitialized so this creates a static checker warning.
But it's harmless, we can just delete it.
