When a new clockevent device is added and replaces a previous device, the latter is put into the released list. Then the released list is added back. This may look counter-intuitive but the reason is that released device might be suitable for other uses. For example a released CPU regular clockevent can be a better replacement for the current broadcast event. Similarly a released broadcast clockevent can be a better replacement for the current regular clockevent of a given CPU. Improve comments stating about these subtleties.

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 reStructuredText 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.
