Including; demoting file header from kerneldoc to standard comment/
header, adding a variety of missing function argument documentation,
repairing formatting (kerneldoc does not like blank lines) and the
demotion of a kerneldoc header which shows no interest in providing
documentation for any of its arguments.

Fixes this the following W=1 issues:
