Commit b24413180f ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") took care of a lot of files
without any license information.
These headers were not processed by the tool perhaps because they
contain "GPL" in the code.
I do not see any license boilerplate in them, so they fall back to
GPL version 2 only, which is the project default.

Modules that uses GPL symbols can no longer be build with kbuild,
the build will fail during the modpost step.
When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol
then warn during modpost so author are actually notified.
The actual license compatibility check is shared with the kernel
to make sure it is in sync.
