Indeed this causes more harm than good. We had support calls regarding the
mlx4 driver because of not incremented MODLE_VERSION()s. If we follow your
and Linus' path we shouldn't just get rid of the KERNEL_VERSION() usage
in media and replace it with a new version, but kill all the versioning
stuff out of media (and others) except for maybe the HW version.

Exactly my reasoning.
