[Intel-gfx] [PATCH 4/4] Revert "drm/amd/display: implement force function in amdgpu_dm_connector_funcs"

[Jani Nikula]

This reverts commit 0ba4a784a14592abed41873e339eab78ceb6e230.

drm_edid_override_connector_update() is *not* supposed to be used by
drivers directly.

>From the documentation:

  Only to be used from drm_helper_probe_single_connector_modes() as a
  fallback for when DDC probe failed during drm_get_edid() and caused
  the override/firmware EDID to be skipped.

It's impossible to unify firmare and override EDID handling and property
updates if drivers mess with this directly.
