Daniele Ceraolo Spurio 02224691cb drm/i915/huc: fix leak of debug object in huc load fence on driver unload 
The fence is always initialized in huc_init_early, but the cleanup in
huc_fini is only being run if HuC is enabled. This causes a leaking of
the debug object when HuC is disabled/not supported, which can in turn
trigger a warning if we try to register a new debug offset at the same
address on driver reload.

To fix the issue, make sure to always run the cleanup code.

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.
