Arnd Bergmann f76c745151 Arm SCMI fixes for v6.1
A bunch of fixes to handle:
 1. A possible resource leak in scmi_remove(). The returned error
    value gets ignored by the driver core and can remove the device and
    free the devm-allocated resources. As a simple solution to be able to
    easily backport, the bind attributes in the driver is suppressed as
    there is no need to support it. Additionally the remove path is cleaned
    up by adding device links between the core and the protocol devices
    so that a proper and complete unbinding happens.
 2. A possible spin-loop in the SCMI transmit path in case of misbehaving
    platform firmware. A timeout is added to the existing loop so that
    the SCMI stack can bailout aborting the transmission with warnings.
 3. Optional Rx channel correctly by reporting any memory errors instead
    of ignoring the same with other allowed errors.
 4. The use of proper device for all the device managed allocations in the
    virtio transport.
 5. Incorrect deferred_tx_wq release on the error paths by using devres
    API(devm_add_action_or_reset) to manage the release in the error path.

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.
