NAK

Please don't use checkpatch without testing the result. And please
don't go around running checkpatch on existing source files to
generate cosmetic patches: checkpatch is useful for new code
contributions but there is no desire in the community to make the
entire existing code base checkpatch-clean (and given this broken
patch, that is not even possible)

checkpatch does not work for linker scripts and this header file is
#include'd by linker scripts exclusively.

If you are looking for ways to start contributing to the linux kernel,
have a look at drivers/staging instead of proposing cosmetic 'fixes'
that break the code.
