register_widget_control is deprecated since version 2.8

Currently receiving this error debugging with define('WP_DEBUG', true);

Notice: register_widget_control is deprecated since version 2.8! Use wp_register_widget_control() instead. in wordpress/wp-includes/functions.php on line 2638

How I’m handling widgets currently from my functions.php file

//theme-name widget setup
function grayghostvisuals_widget(){
    //call register_sidebar wp method as array
    register_sidebar( array(
        'ID'            => 'main-widgets',
        'name'          => 'main',
        'before_widget' => '<article id=&quot;%1$s&quot; class=&quot;widget %2$s&quot;>',
        'after_widget'  => '</article>',
        'before_title'  => '<h3 class=&quot;widget-title&quot;>',
        'after_title'   => '</h3>',
    ));//end main-sidebars

    register_sidebar(array(
        'ID'            => 'footer-widgets',
        'name'          => 'footer',
        'before_widget' => '<article id=&quot;%1$s&quot; class=&quot;widget %2$s&quot;>',
        'after_widget'  => '</article>',
        'before_title'  => '<h3 class=&quot;widget-title&quot;>',
        'after_title'   => '</h3>',
    ));//end footer-sidebars
};
//trigger the theme-name widget
add_action( 'widgets_init' , 'grayghostvisuals_widget' );

footer.php where my sidebar resides for widget display
<?php if( function_exists( ‘dynamic_sidebar’ ) && dynamic_sidebar( ‘footer’ ) ) : ?>
<?php dynamic_sidebar(‘footer widget’) ?>
<?php endif; ?>

Documentation on this is slim so I’m unable to find a resolution to the problem. I’ve found a few questions through the forum but they were closed with no answers displayed for their solution and the Codex for register_widget_control is bare.
