Subject[022/262] drm/radeon/kms: bail early in dvi_detect for digital only connectors
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Alex Deucher <alexander.deucher@amd.com>

commit 5f0a26128d66ef81613fe923d5c288942844ccdc upstream.

DVI-D and HDMI-A are digital only, so there's no need to
attempt analog load detect. Also, skip bail before the
!force check, or we fail to get a disconnect events.
The next patches in the series attempt to fix disconnect
events for connectors with analog support (DVI-I, HDMI-B,
DVI-A).
