[ Upstream commitdb9e64c983] The HDCP 2.2 specification requires the seq_num_v to be monotonically increasing, and repeated seq_num_v needs to be treated as an integrity failure. Make it so. For the first message, seq_num_v must be zero, and is already checked. We can only check for less-than-or-equal for the subsequent messages, where hdcp2_encrypted is true. Discovered using AI-assisted static analysis confirmed by Intel Product Security.

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.
