of_irq_parse_one(@int_gen_dev, i, ...) will leak refcount of @i_th_phandle
int_gen_dev {
...
interrupts-extended = ..., <&i_th_phandle ...>, ...;
...
};
Refcount of @i_th_phandle is increased by of_parse_phandle_with_args()
but is not decreased by API of_irq_parse_one() before return, so causes
refcount leakage.
Rework the refcounting to use __free() cleanup and simplify the code to
have a single call to of_irq_parse_raw().
Also add comments about refcount of node @out_irq->np got by the API.

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.
