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.

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.

These two values will be presented by the debug device in its

valid one. The description strings are changed accordingly.

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.

files are moved to the first line of the file. This makes it more

It also uses // to match the "expected style" as well.

The support for 36-bit addresses originally came with an incorrect
printk format for dma addresses. Felipe changed the format string it
while applying, but the result was still incorrect, since we now have
to pass a pointer to the address instead of the integer value:
drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_tx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:261:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/usb/mtu3/mtu3_qmu.c: In function 'mtu3_prepare_rx_gpd':
drivers/usb/mtu3/mtu3_qmu.c:300:25: error: format '%p' expects argument of type 'void *', but argument 7 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
This fixes the printk argument accordingly.

The time_t type and time_to_tm() function are deprecated because
of y2038 problems. In this driver, they are used to pretty-print
the timestamp of the firmware build. This is fine as long as
we don't get a firmware build past 2038.
Converting to time64_t and time64_to_tm() avoids the deprecated
interfaces and works until 2106, when the firmware-defined
data structure overflows.

USB-serial updates for v4.15-rc1
Here are the USB-serial updates for 4.15-rc1, including:
- three fixes for longstanding issues in garmin_gps and metro-usb which
could lead to NULL-pointer dereferences and memory leaks
- a workaround for broken f81534 firmware-handling of overruns
- f81534 break support, and
- conversion to timer_setup()
Included are also various clean ups and a new qcserial device id.
All have been in linux-next with no reported issues.

The driver used to be developed with legacy GPIO API support. It's
better to use descriptor-based interface for several reasons. First
of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts
nodes, which is essential since different hardware may have different
GPIOs connectivity including the logical value inversion. Secondly,
by requesting the reset GPIO descriptor the driver prevent the other
applications from changing its value. And last but not least the
legacy GPIO interface should be avoided in the new code due to it
obsolescence.

The methods like of_property_read_u32 utilizing the specified
pointer permit only the pointer to a preallocated u32 storage as the
third argument. As a result the driver crashes on NULL pointer
dereference in case if "oc-delay-us" or "power-on-time-ms" declared
in dts file.

USB2517 supports two LED modes: USB mode and speed (default) indication
mode. The last one can be switched on by corresponding dts property.
Since USB251xb hubs doesn't support LEDs settings, we need to ignore
this setting.

Battery charging settings are supported by USB251xb hubs only.
USB2517i isn't one of them. So we need to reflect it within the
device-specific data structure. The driver doesn't support dts
property changing this setting, but instead defaults it with zero.
So the flag isn't used anywhere in the driver, but still can be helpful
in future, when necessity of the corresponding dts setting arises.

USB electrical signaling drive strength boost bit is also supported
by USB2517 hub. Since it got three addition ports, the designers
needed to add one more register for initialization. It turned out
to be formerly reserved 0xF7. As before we just initialize it with
default zeros.

USB2517 got three additionl downstream ports, which can
as well be mapped to another logical ports. USB251xb driver
currently doesn't fully support such setting configuration
from dts file. This patch doesn't change this, but adds
usb2517 spcific ports default liner mapping.
