drm/i915/tv: fix gen4 composite s-video tv-out
This is *not* bisected, but the likely regression is commit c35614380d5c956bfda20eab2755b2f5a7d6f1e7 Author: Zhao Yakui <yakui.zhao@intel.com> Date: Tue Nov 24 09:48:48 2009 +0800 drm/i915: Don't set up the TV port if it isn't in the BIOS table. The commit does not check for all TV device types that might be present in the VBT, disabling TV out for the missing ones. Add composite S-video.
