Is it GPL-2.0, GPL-2.0-only, or GPL-2.0+? Please make sure all license IDs are consistent.


I see drm/vkms is also writing the copyrights similar.

with "# SPDX-License-Identifier: GPL-2.0-only" in the Makefile,

while "// SPDX-License-Identifier: GPL-2.0+" in the C source file.

Sorry, I'm stupid, I can't figure out the difference between them.

Personally, I really don't care about this as along as checkpatch.pl don't complain.

I respect the maintainers of DRM, they didn't told me to change it.

I assume there is no problem.
