[Intel-gfx] [PATCH v4 3/3] drm/i915/hdcp: reuse rx_info for mst stream type1 capability check

2021-08-11 Thread Juston Li
On some MST docking stations, rx_info can only be read after RepeaterAuth_Send_ReceiverID_List and the RxStatus READY bit is set otherwise the read will return -EIO. This behavior causes the mst stream type1 capability test to fail to read rx_info and determine if the topology supports type1 and
