commit1cffb1c664upstream. of_get_child_by_name() increments the reference counter of the OF node it managed to find. So after the code is done using the device node, the refcount must be decremented. Add missing of_node_put() invocation then to the dwc3_qcom_of_register_core() method, since DWC3 OF node is being used only there.

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.
