Sudeep Holla 46dcd68aac firmware: arm_ffa: Unregister the FF-A devices when cleaning up the partitions 
Both the FF-A core and the bus were in a single module before the
commit 18c250bd7e ("firmware: arm_ffa: Split bus and driver into distinct modules").

The arm_ffa_bus_exit() takes care of unregistering all the FF-A devices.
Now that there are 2 distinct modules, if the core driver is unloaded and
reloaded, it will end up adding duplicate FF-A devices as the previously
registered devices weren't unregistered when we cleaned up the modules.

Fix the same by unregistering all the FF-A devices on the FF-A bus during
the cleaning up of the partitions and hence the cleanup of the module.

Fixes: 18c250bd7e ("firmware: arm_ffa: Split bus and driver into distinct modules")

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 reStructuredText 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.
