If a HDCP repeater is detected with zero downstream devices, HDCP spec approves either of below actions: 1. Dont continue on second stage authentication. Disable encryption. 2. Continue with second stage authentication excluding the KSV list and on success, continue encryption. Since disable encryption is agreed, repeater is not expected to have its own display. So there is no consumption of the display content in such setup. Hence, incase of repeater with zero device count, this patch fails the HDCP authentication and stops the HDCP encryption. v2: Rephrased commit msg and added comments in code [Seanpaul] v3: No changes.
