drm/i915: honor forced connector modes v2 (ef34ab89) · Commits · 戴 / test

In the move over to use BIOS connector configs, we lost the ability to force a specific set of connectors on or off. Try to remedy that by dropping back to the old behavior if we detect a hard coded connector config. v2: don't deref connector state for disabled connectors (Jesse) Reported-by:
