Show Username without Link

Using our existing example:

function filter_tml_widget_user_links( $links ) {
	$user = wp_get_current_user();

	$role = reset( $user->roles );
	if ( empty( $role ) ) {
		$role = 'subscriber';
	}
	if ( is_super_admin() ) {
		$role = 'administrator';
	}

	// These links are for authors, editors and admins
	if ( in_array( $role, array( 'author', 'editor', 'administrator' ) ) ) {
		$links = array(
			'dashboard' => array(
				'title' => __( 'Dashboard' ),
				'url'   => admin_url(),
			),
			'profile'   => array(
				'title' => $user->display_name,
				'url'   => admin_url( 'profile.php' ),
			),
			'logout'    => array(
				'title' => __( 'Log Out' ),
				'url'   => wp_logout_url(),
			),
		);

	// These are for all other roles
	} else {
		$links = array(
			'profile'   => array(
				'title' => $user->display_name,
				'url'   => admin_url( 'profile.php' ),
			),
			'logout'    => array(
				'title' => __( 'Log Out' ),
				'url'   => wp_logout_url(),
			),
		);
	}

	return $links;
}
add_filter( 'tml_widget_user_links', 'filter_tml_widget_user_links' );
