Subject: drm/radeon/kms: fix DVO setup on some r4xx chips
From: Alex Deucher <[email protected]>
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.
