"GPL" is enough
I see many projects use GPL v2 here, and all mediatek projects use GPL v2, too. I'm not sure which one is better. Do I need to modify this?
See https://www.kernel.org/doc/html/latest/process/license-rules.html?highlight=...
Loadable kernel modules also require a MODULE_LICENSE() tag. This tag is neither a replacement for proper source code license information (SPDX-License-Identifier) nor in any way relevant for expressing or determining the exact license under which the source code of the module is provided.
“GPL”
Module is licensed under GPL version 2. This does not express any distinction between GPL-2.0-only or GPL-2.0-or-later. The exact license information can only be determined via the license information in the corresponding source files.
“GPL v2”
Same as “GPL”. It exists for historic reasons.
So "GPL v2" is not incorrect but for new contributions you might as well use the recommended tag.
