The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
492 int ab8500_bm_of_probe(struct device *dev,
493 struct device_node *np,
494 struct abx500_bm_data *bm)
495 {
496 const struct batres_vs_temp *tmp_batres_tbl;
497 struct device_node *battery_node;
...
501 /* get phandle to 'battery-info' node */
502 battery_node = of_parse_phandle(np, "battery", 0);
...
509 if (!btech) {
510 dev_warn(dev, "missing property battery-name/type\n");
511 return -EINVAL; ---> leaked here
512 }
...
540 of_node_put(battery_node); ---> released here
541
542 return 0;
543 }

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.
