    Subject[ 02/75] drm/radeon/kms: fix DVO setup on some r4xx chips
    3.3-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Alex Deucher <alexander.deucher@amd.com>

    commit afceb9319f21b18ee3bc15ee9a5f92e18ef8a8c9 upstream.

    Some r4xx chips have the wrong frev in the
    DVOEncoderControl table. It should always be 1
    on r4xx. Fixes modesetting on DVO on r4xx chips
    with the bad frev.

    Reported by twied on #radeon.
