    Subject[ 073/150] drm: shut up invalid edid messages
    Date
    3.8-stable review patch.  If anyone has any objections, please let me know.

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

    From: Maarten Lankhorst <maarten.lankhorst@canonical.com>

    commit f934ec8c34b9dcefb5a4f35b0bda33bca289cbe6 upstream.

    My cheapo monitor has an invalid block 1, resulting in a lot of dmesg spam every few seconds.

    I get it the first time that the entire block is all 0xff..
