commit bec4d7c93afc07dd0454ae41c559513f858cfb83 upstream.
After the device_register() succeeds, then the correct way to clean up
is to call device_unregister(). The unregister calls both device_del()
and device_put(). Since this code was only device_del() it results in
a memory leak.

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.
