From mboxrd@z Thu Jan 1 00:00:00 1970 From: Johan Hovold Subject: [PATCH 9/9] tty: drop unused alt_speed from tty_struct Date: Tue, 6 Jun 2017 12:54:41 +0200 Message-ID: <20170606105441.689-10-johan@kernel.org> References: <20170606105441.689-1-johan@kernel.org> Return-path: In-Reply-To: <20170606105441.689-1-johan@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman Cc: Jiri Slaby , Tony Luck , Fenghua Yu , Samuel Ortiz , "David S. Miller" , linux-kernel@vger.kernel.org, linux-usb@vger.kernel.org, linux-serial@vger.kernel.org, Johan Hovold List-Id: linux-serial@vger.kernel.org Drop the now unused alt_speed field from struct tty_struct. Setting an alt_speed using the ASYNC_SPD flags has been deprecated since v2.1.69, and has been broken for all tty drivers but serial-core since v3.10 and commit 6865ff222cca ("TTY: do not warn about setting speed via SPD_*") without anyone noticing. Note that serial-core still supports changing speed using TIOCSSERIAL and SPD flags (including "alt-speeds"), but also warns about it being deprecated since pre-git.
