The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files (primarily header files) were simply missing the boiler plate and got caught up in the global update. Fixes: b24413180f5 (License cleanup: add SPDX GPL-2.0 license identifier to files with no license) Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Acked-by: Emil Velikov <emil.l.velikov@gmail.com> Acked-by: Karol Herbst <kherbst@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
