Francois Dugast 2750ff97ee drm/xe/hw_engine_group: Add helper to wait for dma fence jobs
This is a required feature for faulting long running jobs not to be
submitted while dma fence jobs are running on the hw engine group.

v2: Switch to lockdep_assert_held_write in worker, get a proper reference
    for the last fence (Matt Brost)

v3: Directly call dma_fence_put with the fence ref (Matt Brost)

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.
