[ Upstream commit 20543be93ca45968f344261c1a997177e51bd7e1 ]
drm_display_info is updated by drm_get_edid() or drm_connector_update_edid_property(). In the amdgpu driver it is almost always updated when the edid is read in amdgpu_connector_get_edid(), but not always. Change amdgpu_connector_get_edid() and amdgpu_connector_free_edid() to keep drm_display_info updated.
