[ Upstream commit 222471f764 ]
In xhci_plat_probe() both sysdev and pdev->dev are being used
for finding quirks. There are some drivers(like dwc3 host.c)
which adds quirks(like usb3-lpm-capable) into pdev and the logic
present in xhci_plat_probe() checks for quirks in either sysdev
or pdev for finding the quirks. Because of this logic, some of
the quirks are getting missed(usb3-lpm-capable quirk added by dwc3
host.c driver is getting missed).This patch fixes this by iterating
over all the available parents for finding the quirks. In this way
all the quirks which are present in child or parent are correctly
updated.

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.
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.
