USB: serial: visor: handle potential invalid device configuration

If we get an invalid device configuration from a palm 3 type device, we
might incorrectly parse things, and we have the potential to crash in
"interesting" ways.

Fix this up by verifying the size of the configuration passed to us by
the device, and only if it is correct, will we handle it.

Note that this also fixes an information leak of slab data.

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.

missing endpoints), but only after the port structures have been setup.

USB: visor: Match I330 phone more precisely

Samsung has just released a portable USB3 SSD, coming in a very small
and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
already used by the Palm Visor driver for the Samsung I330 phone cradle.
Having pl2303 or visor pick up this device ID results in conflicts with
the usb-storage driver, which handles the newly released portable USB3
SSD.

To work around this conflict, I've dug up a mailing list post [1] from a
long time ago, in which a user posts the full USB descriptor
information. The most specific value in this appears to be the interface
class, which has value 255 (0xff). Since usb-storage requires an
interface class of 0x8, I believe it's correct to disambiguate the two
devices by matching on 0xff inside visor.
