From 0db37fa025f0eac64f9fdad49e310d7660f48944 Mon Sep 17 00:00:00 2001
From: =?utf-8?q?Ville=20Syrj=C3=A4l=C3=A4?= <ville.syrjala@nokia.com>

Subject: [PATCH 68/69] DSS2: Swap field offset values w/ VRFB rotation
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
The field 0 and field 1 offset values were still incorrect when VRFB
rotation is used. Swap them to put the fields into proper order.
