The MMAL client_component field is used with the event mechanism to allow the client to identify the component for which the event is generated. The field is only 32bits in size, therefore we can't use a pointer to the component in a 64 bit kernel. Component handles are already held in an array per VCHI instance, so use the array index as the client_component handle to avoid having to create a new IDR for this purpose.

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.
