Vimrc function to clean up current line

Question

I am trying to create a vimrc function which will clean up a line by doing simple substitutions. The function is called upon CARRIAGE RETURN. The function is being called and is cleaning up the line contents. My question is how do I overwrite the previous content with the cleaned up content from inside the function?

function! CleanLine()
  let s = getline( '.' )
  let s = substitute( s, '( )', '()', 'g' )
  let s = substitute( s, ';', '; ', 'g' )
  let s = substitute( s, '(', ' (', 'g' )
  "HOW DO I SET THE CURRENT LINE CONTENT AS s
endfunction
inoremap <CR> <C-R>=CleanLine()<CR>

thanks.
