upgrading to laravel 5.1 - removing guard from base controller gives error

Question

I'm upgrading my app to laravel 5.1 following the upgrade guide in the official docs. It says for authentication

you no longer need to pass the Guard and Registrar instances to the base constructor. You can remove these dependencies entirely from your controller's constructor.

But after removing this from base constructor in AuthController when i try to visit the login page below error is shown

ErrorException in AuthController.php line 41:
Undefined variable: auth

what i'm doing wrong??

Answer 1

Your constructor probably still mentions the following:

//$this->auth = $auth;
//$this->registrar = $registrar;

Just comment these two lines.
