WP_DEBUG gives message that get_current_theme is deprecated

The following is used in the plugin (on line 106 of auto-hide-admin-bar.php):

if (function_exists('get_current_theme')) {
        $theme_name = get_current_theme();
    };

WP_DEBUG is telling me that get_current_theme is deprecated. Could the following be used instead?

if (function_exists('wp_get_theme')) {
    $theme_name = ( wp_get_theme()->Template );
};

(Or change the variable name to $theme_parent would perhaps be better — also on line 117.)

This would also have the advantage of picking up children of Twenty Fourteen as well, which presumably would need the same fix.
