Johan Hovold 872181a79b USB: ledtrig-usbport: fix of-node leak
[ Upstream commit 03310a1548 ]

This code looks up a USB device node from a given parent USB device but
never dropped its reference to the returned node.

As only the address of the node is used for a later matching, the
reference can be dropped immediately.

Note that this trigger implementation confuses the description of the
USB device connected to a port with the port itself (which does not have
a device-tree representation).

Fixes: 4f04c210d0 ("usb: core: read USB ports from DT in the usbport LED trigger driver")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
