This driver was apparently never tested with an actual KLSI device. In
fact, even the device-id entry which was supposed to allow for this had
a typo in it.

Tests now reveal that the predicted firmware differences with the
PalmConnect adapters are real and that the driver does not support KLSI
devices with PID 0x000c, so let's remove the broken entry.

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.

Drop redundant packed attribute from the port-settings struct which is
already 1-byte aligned. Also replace __u8 with u8 for the field types as
this is not a structure we share with user space.

The current implementation failed to detect short transfers when
attempting to read the line state, and also, to make things worse,
logged the content of the uninitialised heap transfer buffer.

Function klsi_105_open() calls usb_control_msg() (to "enable read") and
checks its return value. When the return value is unexpected, it only
assigns the error code to the return variable retval, but does not
terminate the exception path. This patch fixes the bug by inserting
"goto err_generic_close;" when the call to usb_control_msg() fails.
