Fix for Lint warnings

* This commit handles only warnings of mentioned type
  warning:
    comment on exported function <funcname> should be
      of the form "<funcname> ..."
* In this case, there were comments for the exported
  function/constant/var for which warnings raised,
  but not in expected format.
* So this fix is mostly formating the comment to avoid
  lint warnings.

  Observations:
    * comment did not had function name
    * function name in comment was immediately follwed by comma
        => function followed by space and any description is expected
    * function was not mentioned in the first line of the comment
        => when there is multiline comment, first line should start with
           function name
