Arnd Bergmann a316877372 Arm SCMI fixes for v6.2
Few fixes addressing:
 1. Possible compromise with the shorter message size from a misbheaving
    SCMI platform firmware. The shmem accesses are now hardened to handle
    the same in fetch_notification and fetch_response.
 
 2. Possible unsafe locking scenario which is solved by calling
    virtio_break_device() before getting hold of vioch->lock.
 
 3. Possible stale error status reported from a previous message being
    used again as it is not cleared.

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.
