[PATCH v2] drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interrupt

2022-12-25 Thread xurui
HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work
