error with ansible 2.0

[ydawant]

seeing this error:
ERROR! this task 'lineinfile' has extra params, which is only allowed in the following modules: command, shell, script, include, include_vars, add_host, group_by, set_fact, raw, meta

my proposed fix:

in tasks/main.yml replace the double quotes in the "Ensure the hostname entry for master is available for the client." task to single quotes in the address interpolation.

from:
lineinfile: dest=/etc/hosts regexp="{{ mysql_repl_master }}" line="{{ hostvars[mysql_repl_master].ansible_default_ipv4.address + " " + mysql_repl_master }}" state=present

to:
lineinfile: dest=/etc/hosts regexp="{{ mysql_repl_master }}" line="{{ hostvars[mysql_repl_master].ansible_default_ipv4.address + ' ' + mysql_repl_master }}" state=present
