Vladimir Zapolskiy 818e100c2b phy: qcom-qusb2: Fix a memory leak on probe
[ Upstream commit bf7ffcd0069d30e2e7ba2b827f08c89f471cd1f3 ]

On success nvmem_cell_read() returns a pointer to a dynamically allocated
buffer, and therefore it shall be freed after usage.

The issue is reported by kmemleak:

  # cat /sys/kernel/debug/kmemleak

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.
