[ Upstream commit5ca86eae55] Afer commit1fa5ae857b("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically. It needs to be freed when of_device_register() fails. Call put_device() to give up the reference that's taken in device_initialize(), so that it can be freed in kobject_cleanup() when the refcount hits 0. macio device is freed in macio_release_dev(), so the kfree() can be removed.

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.
