USB: serial: qcserial: fix altsetting probing

Drivers should not assume that interface descriptors have been parsed in
any particular order so use the interface number to look up the second
alternate setting. That number is also what the driver later use to
switch setting.

Note that although the driver could end up verifying the existence of
the expected endpoints on the wrong interface, a later sanity check in
usb_wwan_port_probe() would have caught this before it could cause any
real damage.

but need sendsetup = true for the NMEA port to make it work properly.

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking
advantage of the fact that existing devices work with sendsetup = true
too.

Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add
DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID
0x9090.

Tests with several MC73xx/MC74xx/MC77xx devices have been performed in
order to verify backward compatibility.

USB: serial: Remove redundant license text

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

USB: serial: qcserial: expose methods for modem control

The qcserial driver fails to expose the .tiocmget and .tiocmset methods
available from usb_wwan. These methods are required by ioctl commands
dealing with the modem control signals DTR, RTS, etc.

With these methods not set ioctl calls intended to control the DTR state
will fail. For example, pppd drops and raises DTR in preparation to
dialing the modem, which handles the case of the modem already being
connected by making it hang up and return to command mode. DTR control
being unavailable will lead to a protracted failure to connect as the
modem will be stuck in a state not responsive to command.

I have tested that with this patch the described case is handled
successfully. There is an analogous method for .ioctl available from
usb_wwan (as used in option.c) but I conservatively omitted that for
lack of familiarity.

USB: qcserial: Fix support for HP lt4112 LTE/HSPA+ Gobi 4G Modem

The DEVICE_HWI type was added under the faulty assumption that Huawei
devices based on Qualcomm chipsets and firmware use the static USB
interface numbering known from Gobi devices. But this model does
not apply to Huawei devices like the HP branded lt4112 (Huawei me906e).
Huawei firmwares will dynamically assign interface numbers. Functions
are renumbered when the firmware is reconfigured.

Fix by changing the DEVICE_HWI type to use a simplified version
of Huawei's subclass + protocol scheme: Blacklisting known network
interface combinations and assuming the rest are serial.

USB: qcserial: make AT URCs work for Sierra Wireless devices

Three Sierra Wireless modems have been found to require the CDC ACM
SET_CONTROL_LINE_STATE request on the AT port in order to receive
unsolicited response codes, most recently the Dell Wireless 5808e
(which is a re-branded Sierra Wireless EM7355). On the other hand,
the Sierra Wireless MC7710 does not seem to need this request, but
it was found to work either way.

Use this request on the AT port of devices with the Sierra Wireless
layout in the qcserial driver. The other modems that were moved to
the option driver to work around this can now be moved back.

USB: qcserial/option: make AT URCs work for Sierra Wireless MC7305/MC7355

Tests with a Sierra Wireless MC7355 have shown that 1199:9041 devices
also require the option_send_setup() code to be used on the USB
interface for the AT port to make unsolicited response codes work
correctly. Move these devices from the qcserial driver to the option
driver like it has been done for the 1199:68c0 devices in commit
d80c0d14183516f184a5ac88e11008ee4c7d2a2e ("USB: qcserial/option: make

As has been discussed in the thread starting with

Sierra Wireless MC73xx devices with USB VID/PID 0x1199:0x68c0 require the
option_send_setup() code to be used on the USB interface for the AT port
to make unsolicited response codes work correctly. Move these devices from

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

usb: qcserial: add a number of Dell devices

"The Dell drivers use the same configuration for PIDs:

81A2: Dell Wireless 5806 Gobi(TM) 4G LTE Mobile Broadband Card
81A3: Dell Wireless 5570 HSPA+ (42Mbps) Mobile Broadband Card
81A4: Dell Wireless 5570e HSPA+ (42Mbps) Mobile Broadband Card

These devices are all clearly Sierra devices, but are also definitely

Fix port-data memory leak in usb-serial probe error path by moving port
data allocation to port_probe.

Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect
with a port_remove hook") port data is deallocated in port_remove. This
leaves a possibility for memory leaks if usb-serial probe fails after
attach but before the port in question has been successfully registered.

Note that this patch also fixes two additional memory leaks in the error
path of attach should port initialisation fail for any port as the urbs
were never freed and neither was the data of any of the successfully
initialised ports.

Compile-only tested.

USB: qcserial: fix port handling on Gobi 1K and 2K+

Bjorn's latest patchset does break Gobi 1K and 2K because on both
devices as it claims usb interface 0. That's because usbif 0 is not
handled in the switch statement, and thus the if0 gets claimed when it
should not. So let's just make things even simpler yet, and handle both
the 1K and 2K+ cases separately. This patch should not affect the new
Sierra device support, because those devices are matched via
interface-specific matching and thus should never hit the composite
code.

usb: usb_wwan: replace release and disconnect with a port_remove hook

Doing port specific cleanup in the .port_remove hook is a
lot simpler and safer than doing it in the USB driver
.release or .disconnect methods. The removal of the port
from the usb-serial bus will happen before the USB driver
cleanup, so we must be careful about accessing port specific
driver data from any USB driver functions.

This problem surfaced after the commit

0998d0631 device-core: Ensure drvdata = NULL when no driver is bound

which turned the previous unsafe access into a reliable NULL
pointer dereference.

USB: qcserial: adding Sierra Wireless devices

The QMI mode of the Sierra Wireless MC7710 is close to
a Gobi device, and also identified as one by the
Windows drivers provided by Sony. The serial interfaces
are the same as for any other Gobi module, but the USB
interface layout is different:

0: DM/DIAG (also present in bootloader mode)
2: NMEA
3: AT-capable modem port
8: QMI/net
19: QMI/net (not always present)
20: QMI/net (not always present)

Note in particular that the NMEA and AT ports are reversed
compared to a Gobi 2k+ device, and that the DM port appears
as a QDL port in bootloader mode using the same device ID.

The Sony driver also document two new devices with standard
Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode
(1199:68a4, 1199:68a8). Adding these as well.

Lenovo Windows drivers document the USB interface layout
for a few additional Sierra Wireless devices. Adding these
while at it:
- MC7770 (1199:901b) with standard Gobi 2k+ layout
- MC7700 (0f3d:68a2) with the same layout as MC7710
- MC7750 (114f:68a2) with the same layout as MC7710
- EM7700 (1199:901c) with the same layout as MC7710

USB: serial: rework usb_serial_register/deregister_drivers()

This reworks the usb_serial_register_drivers() and
usb_serial_deregister_drivers() to not need a pointer to a struct
usb_driver anymore. The usb_driver structure is now created dynamically

This saves lines of code in each usb-serial driver. All in-kernel users
of these functions were also fixed up at this time. The pl2303 driver
was tested that everything worked properly.

Thanks for the idea to do this from Alan Stern.

usb-serial: clean up unneeded PM-related fields

This patch (as1551) cleans up the PM-related entries in the usb_driver
structures of the various USB serial driver modules. Those entries
are now filled in by the usb-serial core during driver registration,
so they don't need to be initialized explicitly in the source code.

The same is true of the one remaining no_dynamic_id entry.

reset_resume remains a small problem, because the serial core doesn't
support it. The patch ignores these entries.

USB: qcserial: Enable Diagnostics Monitor and GPS ports on Gobi 2000

this patch to qcserial.c enables the Diagnostics Monitor
and NMEA GPS ports on Qualcomm Gobi 2000 devices.

A Gobi 2000 device will provide 3 serial ports:
# /dev/ttyUSB0 -> Diagnostics
# /dev/ttyUSB1 -> 3G Modem
# /dev/ttyUSB2 -> NMEA GPS port

* The Diagnostics Monitor uses Qualcomm's DM protocol; I used
libqcdm (ModemManager) to talk to it, found it working, but at
least DM commands 12 and 64 are not implemented on my device
(Gobi 2000 built into Thinkpad x100e).

* Functionality of the 3G Modem port remains unchanged.

* The GPS port and how to enable it has been confirmed now in the
Gobi 3000 source code at:
https://www.codeaurora.org/patches/quic/gobi/
Enable/disable GPS via:
echo "\$GPS_START" > /dev/ttyUSB2
# use GPS
