[PATCH 6/7] drm/i915/mst: ack sink irq ESI for link status changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Only specific event status indicators caused the link status to be
acked. Be sure to ack the link status change event.

Arguably we should track which bits to actually clear in ESI instead of
the wholesale approach.
