Yuan Can fe880e9df9 tpm/tpm_ftpm_tee: Fix error handling in ftpm_mod_init()
[ Upstream commit 2b7d07f7ac ]

The ftpm_mod_init() returns the driver_register() directly without checking
its return value, if driver_register() failed, the ftpm_tee_plat_driver is
not unregistered.

Fix by unregister ftpm_tee_plat_driver when driver_register() failed.

Fixes: 9f1944c23c ("tpm_ftpm_tee: register driver on TEE bus")

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.
