CEC adapters and controllers (handlers) are now set up as follows: 1. Allocate CEC adapters: setup of control handlers in next step requires these adapters to be allocated. 2. Setup of control handlers: This must be done prior to registering and exposing the adapters to user space to avoid a race condition. 3. Register CEC adapters: make them available to user space.

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.
