[Intel-gfx] [PATCH] drm/i915/sdvo: Use intel_sdvo-ddc instead of intel_sdvo-i2c for DDC.
In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC. Thus the code will always have to rely on a LVDS panel mode supplied by VBT. In most cases this succeeds, so this didn't get detected for quite a while.
