Subject: [PATCH v3] net: iucv: Free memory obtained by kzalloc
Date:   Thu,  1 Mar 2018 17:01:57 +0530

Precedence: bulk

Free memory by calling put_device(), if afiucv_iucv_init is not
successful.

changes in v2:
             Calling put_device() before kfree().
changes in v3:
             No need to call kfree(). So removed kfree().
