Ramalingam C f179a2fc2e drm/i915: Stop encryption for repeater with no sink
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.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
