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.

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.

PCI-SIG has defined Interface FEh for Base Class 0Ch, Sub-Class 03h as "USB
Device (not host controller)". It is already being used in various USB
device controller drivers for matching, so add PCI_CLASS_SERIAL_USB_DEVICE
and use it.

Add 'match_ep' callback to utilize chip-specific knowledge in endpoint matching
process. Function does the same that was done by chip-specific code inside
of epautoconf. Now this code can be removed from there to separate generic code
from platform specific logic.

The seq_printf/seq_puts/seq_putc return values, because they
are frequently misused, will eventually be converted to void.

seq_has_overflowed() and make public")
Miscellanea:
o Coalesce formats, realign arguments
o Create static functions for statement expression macros
o Use c90 style comments instead of c99

now that no UDC driver relies on the extra
'driver' argument to ->udc_stop(), we can
safely remove it.
This commit is based on previous work by
Robert Baldyga <r.baldyga@samsung.com> which
can be found at [1]; however that patch turned
out to have a high probability of regressing
many UDC drivers because of a blind search & replace
s/driver/$udc->driver/ which caused the 'driver'
argument to stop_activity() to be a valid non-NULL
pointer when it should be NULL, thus causing UDCs
to mistakenly call gadget driver's ->disconnect()
callback.

Use the recently introduced usb_gadget_giveback_request() in favor of
direct invocation of the completion routine.
All places in drivers/usb/ matching "[-.]complete(" were replaced with a
call to usb_gadget_giveback_request(). This was compile-tested with all
ARM drivers enabled and runtime-tested for musb.
