[ 075/149] drm/radeon/kms: fix analog load detection on DVI-I connectors

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

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

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit e00e8b5e760cbbe9067daeae5454d67c44c8d035 upstream.

We digital encoders have a detect function as well (for
DP to VGA bridges), so we make sure we choose the analog
one here.

Fixes:
