Nicholas Kazlauskas c40a09e56f drm/amd/display: Add callbacks for DMUB HPD IRQ notifications ... [Why] We need HPD IRQ notifications (RX, short pulse) to properly handle DP MST for DPIA connections. [How] A null pointer exception currently occurs when these are received so add a check to validate that we have a handler installed for the notification. Extend the HPD handler to also handle HPD IRQ (RX) since the logic is the same.
