From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jaejoong Kim Subject: [PATCH 06/25] tty: hvc: hvcs: Change return type to void Date: Tue, 4 Sep 2018 11:44:32 +0900 Message-ID: <1536029091-4426-7-git-send-email-climbbb.kim@gmail.com> References: <1536029091-4426-1-git-send-email-climbbb.kim@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1536029091-4426-1-git-send-email-climbbb.kim@gmail.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: driverdev-devel-bounces@linuxdriverproject.org Sender: "devel" To: linux-um@lists.infradead.org, netdev@vger.kernel.org, linux-mmc@vger.kernel.org, linux-s390@vger.kernel.org, devel@driverdev.osuosl.org, greybus-dev@lists.linaro.org, linuxppc-dev@lists.ozlabs.org, linux-serial@vger.kernel.org, sparclinux@vger.kernel.org, linux-usb@vger.kernel.org, linux-bluetooth@vger.kernel.org, linux-kernel@vger.kernel.org Cc: Greg Kroah-Hartman , Jiri Slaby List-Id: linux-serial@vger.kernel.org Since tty_port_install() always returns 0, the return type has changed to void. Now apply this and remove the obsolete error check.
