Sean Paul 01468d6c71 drm/i915: Only disable HDCP when it's active
Instead of always trying to disable HDCP. Only run hdcp_disable when the
state is not UNDESIRED. This will catch cases where it's enabled and
also cases where enable failed and the state is left in DESIRED mode.

Note that things won't blow up if disable is attempted while already
disabled, it's just bad form.

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.
