From bb364e76f1ed71ff22d58c7b9fa08c04a2b7e056 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0007/1453] drm/amdgpu: poll ras_controller_irq and
err_event_athub_irq status
For the hardware that can not enable BIF ring for IH cookies for both
ras_controller_irq and err_event_athub_irq, the driver has to poll the
status register in irq handling and ack the hardware properly when there
is interrupt triggered
