[PATCH 1/4] drm: retrieve EDID via ACPI _DDC method
...er ideas if you have them, but didn't see a good way to
search for the "right" _DDC implementation should there be more than one.
As for preventing the ACPI EDID retrieval from being used for external
panels, I've done this in the individual DRM drivers that call into the
new drm_edid_acpi() API since it seemed that each DRM driver had its own
way of distinguishing display connector types. If there's a good way to
filter for internal panels in DRM core, I'd be happy to do that instead.

Fall back to retrieving the EDID via the ACPI _DDC method, when present
for notebook internal panels, when retrieving BIOS-embedded EDIDs.
