Problem with var in ansible 2.2

[rob42]

These lines in main.yml fail in 2.2, the syntax has changed:

- name: Ensure hostname entries in /etc/hosts
  lineinfile:
    dest: /etc/hosts
    regexp: "{{item.regexp}}"
    line: "{{item.line}}"
    state: present
  with_items: hostname_hosts_file

Need to change last line to:

  with_items: "{{hostname_hosts_file}}"
