   8 commit 602ad43c3cd8f15cbb25ce9bb494129edb2024ed upstream.
   9
  10 This partially reverts 20543be93ca45968f344261c1a997177e51bd7e1.
  11
  12 Calling drm_connector_update_edid_property() in
  13 amdgpu_connector_free_edid() causes a noticeable pause in
  14 the system every 10 seconds on polled outputs so revert this
  15 part of the change.
