Currently the registration and free of beep input device was done manually from the register and the disconnect callbacks of the assigned codec object. This seems working in most cases, but this may be a cause of some races at probe. Moreover, due to these manual calls, the total code became unnecessarily lengthy. This patch rewrites the beep registration code to follow the standard sound device object style. This allows us reducing the code, in addition to avoiding the nested device registration calls.

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.
