drm_edid_to_eld() sets ELD connector type since commit1d1c366507("drm/edid: set ELD connector type in drm_edid_to_eld()"). Remove the redundant update. (Commitc945b8c14b("drm/edid: build ELD in drm_add_edid_modes()") and commitd471ed04b4("drm/drivers: drop redundant drm_edid_to_eld() calls") are also related.) v2: Rebase, update commit message with commit references.
