Currently, if drm.debug is enabled, we get a DRM_ERROR message on the intermediate edid reads. This causes transient failures in CI which flags up the sporadic EDID read failures, which are recovered by rereading the EDID automatically. This patch combines the reporting done by drm_do_get_edid() itself with the bad block printing from get_edid_block(), into a single warning associated with the connector once all attempts to retrieve the EDID fail. v2: Print the whole EDID, marking up the bad/zero blocks. This requires recording the whole of the raw edid, then a second pass to reduce it to the valid extensions. v3: Fix invalid/valid extension fumble.
