There are two bugs in the error handling: 1: If devm_of_phy_provider_register() fails then there was no cleanup. 2: The error handling called of_node_put(child) improperly leading to a use after free. We are only holding the reference inside the loop so the last two gotos after the loop lead to a use after free bug. Fix this by cleaning up the partial allocations (or partial iterations) in the loop before doing the goto.

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.
