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. > Any upstream driver should never use KERNEL_VERSION().
