Subject: [PATCH 13/25] usb: xhci: dbc: Change return type to void
Date:   Tue,  4 Sep 2018 11:44:39 +0900
Message-Id: <1536029091-4426-14-git-send-email-climbbb.kim@gmail.com>
In-Reply-To: <1536029091-4426-1-git-send-email-climbbb.kim@gmail.com>
References: <1536029091-4426-1-git-send-email-climbbb.kim@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since tty_port_install() always returns 0, the return type has changed
to void. Now apply this and remove the obsolete error check.
