Alexander Usyskin 783100f6ea mei: bus-fixup: set timeout for MKHI send operations
Set a timeout for MKHI client send operations in the bus fixup routines
to prevent potential lock-ups on the cl_bus_lock mutex.
In rare conditions, such as when the i915 or Xe driver is stopping and
not routing interrupts or when GSC FW is in unexpectedly reset the fixup
routines can get stuck.

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.
