Ramalingam C 6498bf5800 drm: revocation check at drm subsystem
On every hdcp revocation check request SRM is read from fw file
/lib/firmware/display_hdcp_srm.bin

SRM table is parsed and stored at drm_hdcp.c, with functions exported
for the services for revocation check from drivers (which
implements the HDCP authentication)

This patch handles the HDCP1.4 and 2.2 versions of SRM table.

v2:
  moved the uAPI to request_firmware_direct() [Daniel]
v3:
  kdoc added. [Daniel]
  srm_header unified and bit field definitions are removed. [Daniel]
  locking improved. [Daniel]
  vrl length violation is fixed. [Daniel]
v4:
  s/__swab16/be16_to_cpu [Daniel]
  be24_to_cpu is done through a global func [Daniel]
  Unused variables are removed. [Daniel]
  unchecked return values are dropped from static funcs [Daniel]

README

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.
