The USB kerneldoc says that the actual_length field "is read in
non-iso completion functions", but the usbfs driver uses it for all
URB types in processcompl(). Since not all of the host controller
drivers set actual_length for isochronous URBs, programs using usbfs
with some host controllers don't work properly. For example, Minas
reports that a USB camera controlled by libusb doesn't work properly
with a dwc2 controller.
It doesn't seem worthwhile to change the HCDs and the documentation,
since the in-kernel USB class drivers evidently don't rely on
actual_length for isochronous transfers. The easiest solution is for
usbfs to calculate the actual_length value for itself, by adding up
the lengths of the individual packets in an isochronous transfer.

usb_control_msg() will return the amount of bytes transferred, if that

Now that the SPDX tag is in all USB files, that identifies the license

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

like the address (sometimes incorrect) for the FSF which is never

Due to these typec files being moved into the drivers/usb/ directory in
this tree, they missed the larger "add SPDX tags to all files" work. So
add the correct SPDX license tag, 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.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
This updates the remaining drivers/usb/*Makefile* that were missing SPDX
identifiers. They all get the following identifier:
SPDX-License-Identifier: GPL-2.0
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This gets rid of the deprecated do_gettimeofday() function in usbip.
The comment above vgadget_get_frame() mentions that it suffers
from issues with the time jumps due to suspend and settimeofday,
so I'm changing it to use ktime_get_ts64() to use monotonic times
that don't have this problem.
I couldn't tell whether we should use CLOCK_MONOTONIC or
CLOCK_MONOTONIC_RAW here, the difference being the exact rate
when correcting for NTP. I picked monotonic time since it doesn't
change the speed to the existing code and should be better
synchronized with other machines we talk to.

vgadget_get_frame returns a frame number from 0 to 2046, which
may require an expensive division operation to wrap at one lower
than the usual number.
I can't see any reason for this, and all other drivers wrap at
a power-of-two number. My best explanation is that it was a simple
typo, so I'm changing the % modulo operator into a cheaper bitmask
that the other drivers use, to make it wrap after 0x7ff rather than
before it.

The product ID for "Linux USB GDB Target device" has been
changed. Change the driver binding table accordingly.
This patch should be back-ported to kernels as old as v4.12,
that contain the commit 57fb47279a04 ("usb/serial: Add DBC
debug device support to usb_debug").

The DbC register set defines an interface for system software
to specify the vendor id and product id for the debug device.
These two values will be presented by the debug device in its
device descriptor idVendor and idProduct fields.
The current used product ID is a place holder. We now have a
valid one. The description strings are changed accordingly.
This patch should be back-ported to kernels as old as v4.12,
that contain the commit aeb9dd1de98c ("usb/early: Add driver
for xhci debug capability").

Several GPL-2.0 drivers used "GPL" rather than "GPL v2" in their
MODULE_LICENSE macros; fix the macros to match the licenses.

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.
