Subject: serial: core: Fix iotype userspace breakage
From: Peter Hurley <peter@xxxxxxxxxxxxxxxxxx>
commit 2bb785169e9709d41220e5c18b0270883a82f85c upstream.
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.
