Ben Horgan f5915600cc platform: Define platform_device_put cleanup handler
Define a cleanup helper for use with __free to destroy platform devices
automatically when the pointer goes out of scope. This is only intended to
be used in error cases and so should be used with return_ptr() or
no_free_ptr() directly to avoid the automatic destruction on success.

A first use of this is introduced in a subsequent commit.

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.
