Fabrizio Castro b18db3a4fa irqchip/renesas-rzg2l: Fix missing put_device 
[ Upstream commit d038109ac1 ]

rzg2l_irqc_common_init() calls of_find_device_by_node(), but the
corresponding put_device() call is missing.  This also gets reported by
make coccicheck.

Make use of the cleanup interfaces from cleanup.h to call into
__free_put_device(), which in turn calls into put_device when leaving
function rzg2l_irqc_common_init() and variable "dev" goes out of scope.

To prevent that the device is put on successful completion, assign NULL to
"dev" to prevent __free_put_device() from calling into put_device() within
the successful path.

"make coccicheck" will still complain about missing put_device() calls,
but those are false positives now.

README 

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.
