<content type='text'>
commit 985616f0457d9f555fff417d0da56174f70cc14f upstream.

The write-URB busy flag was being cleared before the completion handler
was done with the URB, something which could lead to corrupt transfers
due to a racing write request if the URB is resubmitted.

Fixes: 507ca9bc0476 ("[PATCH] USB: add ability for usb-serial drivers to determine if their write urb is currently being used.")

<title>USB: serial: ftdi_sio: add support for FreeCalypso JTAG+UART adapters</title>

<id>urn:sha1:a71ec88ae6a61ac69854b4ef60c0c7920b225e31</id>
<content type='text'>
commit 6cf87e5edd9944e1d3b6efd966ea401effc304ee upstream.

There exist many FT2232-based JTAG+UART adapter designs in which
FT2232 Channel A is used for JTAG and Channel B is used for UART.
The best way to handle them in Linux is to have the ftdi_sio driver
create a ttyUSB device only for Channel B and not for Channel A:
a ttyUSB device for Channel A would be bogus and will disappear as
soon as the user runs OpenOCD or other applications that access
Channel A for JTAG from userspace, causing undesirable noise for
users.  The ftdi_sio driver already has a dedicated quirk for such
JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs
to such adapters and adding these IDs to the driver with the
ftdi_jtag_quirk applied.

Boutique hardware manufacturer Falconia Partners LLC has created a
couple of JTAG+UART adapter designs (one buffered, one unbuffered)
as part of FreeCalypso project, and this hardware is specifically made
to be used with Linux hosts, with the intent that Channel A will be
accessed only from userspace via appropriate applications, and that
Channel B will be supported by the ftdi_sio kernel driver, presenting
a standard ttyUSB device to userspace.  Toward this end the hardware
manufacturer will be programming FT2232 EEPROMs with custom USB IDs,
specifically with the intent that these IDs will be recognized by
the ftdi_sio driver with the ftdi_jtag_quirk applied.

<title>USB: serial: option: support dynamic Quectel USB compositions</title>

<content type='text'>
The USB composition, defining the set of exported functions, is dynamic
in newer Quectel modems.  Default functions can be disabled and
alternative functions can be enabled instead.  The alternatives
includes class functions using interface pairs, which should be
handled by the respective class drivers.

Active interfaces are numbered consecutively, so static
blacklisting based on interface numbers will fail when the
composition changes.  An example of such an error, where the
option driver has bound to the CDC ECM data interface,
preventing cdc_ether from handling this function:

 T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 0

Another device with the same id gets correct drivers, since the
interface of the network function happens to be blacklisted by option:

Change rules for EC21, EC25, BG96 and EG95 to match vendor specific
serial functions only, to prevent binding to class functions. Require
2 endpoints on ff/ff/ff functions, avoiding the 3 endpoint QMI/RMNET
network functions.

<id>urn:sha1:1ac698790819b83f39fd7ea4f6cdabee9bdd7b38</id>
<content type='text'>
These modules have 2 different USB layouts:

The default layout with PID 0x9205 (AT+CUSBSELNV=1) exposes 4 TTYs and
an ECM interface:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  6 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9205 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 1 Cls=02(commc) Sub=06 Prot=00 Driver=cdc_ether
  I:  If#=0x5 Alt= 1 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=cdc_ether

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: AT-capable port (data).

In the secondary layout with PID=0x9206 (AT+CUSBSELNV=86) the module
exposes 6 TTY ports:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  8 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=02(commc) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9206 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x5 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: QFLOG interface.
 * ttyUSB4: DAM interface.
 * ttyUSB5: AT-capable port (data).
