"GPL v2" is the same as "GPL" here, it does not have any additional meaning.

https://www.kernel.org/doc/html/latest/process/license-rules.html

“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.
