Zhengchao Shao 628de998a3 test_firmware: fix memory leak in test_firmware_init()
[ Upstream commit 7610615e8cdb3f6f5bbd9d8e7a5d8a63e3cabf2e ]

When misc_register() failed in test_firmware_init(), the memory pointed
by test_fw_config->name is not released. The memory leak information is
as follows:
unreferenced object 0xffff88810a34cb00 (size 32):
  comm "insmod", pid 7952, jiffies 4294948236 (age 49.060s)
  hex dump (first 32 bytes):

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.
