In nvec_kbd_probe(), the return value of devm_input_allocate_device()
should be checked before it is used.

Now that the SPDX tag is in all drivers/staging/nvec/ 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.
Fix up the staging nvec driver to have a proper SPDX identifiers, 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.

A platform_driver does not need to set an owner, it will be populated by the

Disable device functions and unregister notifier if available. The
serio device must not be "kzallocated". Otherwise serio_unregister_port
will fail because the device is already freed.

When the caps lock key is pressed, toggle the associated

we sent 0x07, but this does not appear to work correctly
on the AC100.

Rewrite the interrupt handler to use a state machine similar to
that found in the various kernels for the Advent Vega. This also
changes the code to use the new functions introduced in the
previous commits.
This also merges the rewrite sent in August 2011 by Marc
Dietrich, and thus also includes code by him. His original
patch can be found on the mailing list.

This patch adds support for LEDs connect to a nvec. A single brightness
property is exported to sysfs. LEDs are selected via bitfields in the
brightness value. Also the blinking behavior is selected through this
method. Vendors may use different values for different HW designs.
