Sorry, but I can't see any advantage on it. On the downside, it
includes the media controller header file (media.h) where it
is not needed.

That's said, some of the above shouldn't be using KERNEL_VERSION
at all. The V4L2 core sets the version already. So, drivers like
cx25821, s3c-camif, bcm2048 and atomisp are likely doing the wrong
