The current kernel-ark build-os branch fails to build due to this error from the self-tests:

   ERROR: The kernel RPM spec file License: field does not match the licenses available in the source tree. Fedora, Centos Stream, and RHEL require that the RPM License field match the licenses in the source tree. See https://docs.fedoraproject.org/en-US/legal/license-approval/ for further information. A list of licenses can be generated by executing the redhat/scripts/license/kspdx.py utility. New licenses can be added to the RPM License field only if they are listed in the Allowed Licenses list https://docs.fedoraproject.org/en-US/legal/allowed-licenses/). Licenses cannot be added if they are in the 'Not Allowed' Licenses (https://docs.fedoraproject.org/en-US/legal/not-allowed-licenses/). Licenses can be added to the 'Allowed' or 'Not Allowed' Licenses by following the License Review Process (https://docs.fedoraproject.org/en-US/legal/license-review-process/).

This occurs because the staging tnt4882 driver has a SPDX license identifier that is not compliant with the official licenses listed (https://spdx.org/licenses).  I have submitted a patch upstream to resolve the issue that has been accepted into linux-next which can be backported into kernel-ark until the patch appears in linux main.

Subject: staging: Fix tnt4882 license to be SPDX compliant

"GPL-2" is not a valid SPDX license identifier[1]. Update to SPDX
compliant string "GPL-2.0-only".
