Subject: [PATCH] drm: shut up invalid edid messages
Date: Tue, 29 Jan 2013 14:27:39 +0100 [thread overview]
Message-ID: <5107CE4B.6020309@canonical.com> (raw)
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..
