[Intel-gfx] [PATCH 0/7] Minor DisplayPort cleanup

[Adam Jackson]

Patch 1 is actually core drm, and independent of the rest of the series.
The rest vary among cosmetic cleanup, unifying the G4X/IRL paths, and
one corner-case change to be more strictly spec-compliant.

Tested on a Thinkpad T500 (GM45) with various DisplayPort attachments.
My X200 (with DP only on the dock) is still not especially reliable, but
I'm sure I'll figure something out.
