From: Peter Hurley Subject: [PATCH] serial: core: Fix iotype userspace breakage Date: Sun, 1 Mar 2015 10:18:16 -0500 Message-ID: <1425223096-17635-1-git-send-email-peter@hurleysoftware.com> Return-path: Sender: stable-owner@vger.kernel.org To: Greg Kroah-Hartman Cc: linux-serial@vger.kernel.org, Peter Hurley , Kevin Cernekee , stable@vger.kernel.org List-Id: linux-serial@vger.kernel.org commit 3ffb1a8193bea ("serial: core: Add big-endian iotype") re-numbered userspace-dependent values; ioctl(TIOCSSERIAL) can assign the port iotype (which is expected to match the selected i/o accessors), so iotype values must not be changed.
