From 2bb785169e9709d41220e5c18b0270883a82f85c Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sun, 1 Mar 2015 10:18:16 -0500 Subject: [PATCH] serial: core: Fix iotype userspace breakage 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.
