    Subject[51/71] drm/radeon/kms: fix extended lvds info parsing
    2.6.38-stable review patch.  If anyone has any objections, please let us know.

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

    From: Alex Deucher <alexdeucher@gmail.com>

    commit 05fa7ea7d23980de0014417a0e0af2048a0f9fc1 upstream.

    On rev <= 1.1 tables, the offset is absolute,
    on newer tables, it's relative.
