[Why] We need to do this to support HDCP over MST Currently we save a display per link, in a MST case we need to save multiple displays per link. [How] We can create an array per link to cache the displays, but it complicates the design. Instead we can use the module to cache the displays. Now we will always add all the displays to the module, but we use the adjustment flag to disable hdcp on all of them before they are added. When we want to enable hdcp we just query the display(cache), remove it then add it back with different adjustments. Its the similar for disable.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
