Don't let the ghost eDP haunt us

From: Paulo Zanoni <[email protected]>

Hi

This week I sent a patch called "drm/i915: propagate errors from intel_dp_init_connector" to fix a Haswell bug that was preventing my machine from booting. Chris provided a nice suggestion for it, so this series should implement his suggestion, but split in a few patches. While writing this code I also spotted a few other things, so there are some patches for them here. Patch 3 is the real bug fix and patches 4 & 5 implement Chris's suggestions. Patch 1 is another bug fix and patches 2, 6, 7 & 8 are my bikesheds for the current code.

Thanks,
Paulo
