2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Chris Wilson <[email protected]> commit 97aaf910731b03b27b1c4c8a58006a1dc99dcd9a upstream. Alex Fiestas reported an issue with his HDMI connector being misdetected as DVI unless he had something connected upon boot. By moving the decision as to whether to use HDMI or DVI encoding for the HDMI capable output until we probe the monitor means that we should avoid sending a HDMI signal to a DVI monitor and also correctly detect hardware like Alex's. However, to really determine what connector is soldered onto the wire we need to inspect the VBT sdvo child devices - but can we trust it?
