When ansible do not load the file host_vars/{{ ansible_hostname }}.yml and host_vars/default.yml it will show syntactic err, so add keyword "skip" to fix it. 

Exit the playbook if the user not define devices  in both  host_vars/{{ ansible_hostname }}.yml and host_vars/default.yml
host_vars/default.yml
