Clean way of making changes to login widget function?

Hi,

What’s a clean way of a making simple changes to the function geodir_loginwidget_output from the file general_functions.php line 3225 ?

All I need to do is move the line

<?php do_action( 'login_form' ); ?>

up 14 lines or so to go above the form between 3223 and 3224.

I noticed that the function geodir_loginwidget_output wasn’t being called by add_action, which is the only way I would have known to remove the action and add a new one.

I’d appreciate a tip on how to go about customizing this.

Best,
Marc
