Subject[PATCH 05/27] audit: kill audit_prepare_user_tty
From: "Eric W. Biederman" <ebiederm@xmission.com>

Now that netlink messages are processed in the context of the sender
tty_audit_push_task can be called directly and audit_prepare_user_tty
which only added looking up the task of the tty by process id is
not needed.
