Please leave the subsystem identification text outside the []. 
Documentation/SubmittingPatches section 15 has details.

It's fairly dopey to have static function declarations in a header file
- no other .c fail can _use_ them, so they may as well be tucked away
inside their .c file.  And that's only needed if the functions indeed
need to be forward-declared.
