The only reason that remains, to why the ARM cpuidle driver calls cpuidle_register_driver(), is to avoid printing an error message in case another driver already have been registered for the CPU. This seems a bit silly, but more importantly, if that is a common scenario, perhaps we should change cpuidle_register() accordingly instead. In either case, let's consolidate the code, by converting to use cpuidle_register|unregister(), which also avoids the unnecessary allocation of the struct cpuidle_device.

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.
