Krzysztof Kozlowski f3498650df usb: dwc3: st: fix probed platform device ref count on probe error path
commit ddfcfeba891064b88bb844208b43bef2ef970f0c upstream.

The probe function never performs any paltform device allocation, thus
error path "undo_platform_dev_alloc" is entirely bogus.  It drops the
reference count from the platform device being probed.  If error path is
triggered, this will lead to unbalanced device reference counts and
premature release of device resources, thus possible use-after-free when
releasing remaining devm-managed resources.

README

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.
