commit 0b9fcab1b8608d429e5f239afb197de928d4de7d upstream.
Commit 01af542392b5 ("usb: ulpi: fix double free in
ulpi_register_interface() error path") removed kfree(ulpi) from
ulpi_register_interface() to fix a double-free when device_register()
fails.
But when ulpi_of_register() or ulpi_read_id() fail before
device_register() is called, the ulpi allocation is leaked.
Add kfree(ulpi) on both error paths to properly clean up the allocation.

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.
