IMO this comment doesn't really add anything: the below WARN_ON already
says as much.  Also the location of the comment right above the function
is confusing: someone not familiar with the code might wonder why the
function is called klp_module_going() if the module can be either coming
or going.  So I think the comment can just be removed.
