More generally speaking, I'd like to see all the 
-Wmissing-declarations/-Wmissing-prototypes warnings addressed
in the kernel and turn on that warning by default.

If there are parts of vc04_services that are intentionally
left in place but currently unused, adding a declaration in the
header file with a comment should be sufficient to prevent it
from getting deleted or seeing bogus warnings.
