>Subject: [PATCH 1/2] drm/radeon/kms: bail early in dvi_detect for digital only connectors
>
>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).
