commit 5ebdc6be16c2000e37fcb8b4072d442d268ad492 upstream.
_of_phy_get() will directly return when suffers of_device_is_compatible()
error, but it forgets to decrease refcount of OF node @args.np before error
return, the refcount was increased by previous of_parse_phandle_with_args()
so causes the OF node's refcount leakage.
Fix by decreasing the refcount via of_node_put() before the error return.

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.
