From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Hurley Subject: [PATCH tty-next 21/22] serial: core: Remove superfluous ldisc flush from uart_close() Date: Mon, 16 Jun 2014 09:17:18 -0400 Message-ID: <1402924639-5164-22-git-send-email-peter@hurleysoftware.com> References: <1402924639-5164-1-git-send-email-peter@hurleysoftware.com> Return-path: In-Reply-To: <1402924639-5164-1-git-send-email-peter@hurleysoftware.com> Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman Cc: linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, One Thousand Gnomes , Peter Hurley List-Id: linux-serial@vger.kernel.org The tty_ldisc_flush() after port hardware shutdown is unnecessary; the ldisc flush was just performed before the hardware shutdown in tty_port_close_start() and the ldisc will be released when uart_close() returns (because the last port close implies the last tty close).
