When the last reference of a gem object is removed it is added to the mm.free_list list and mm.free_work is queued to actually free the object. So gem objects that had their last reference removed by display during drm_atomic_helper_shutdown() are added to mm.free_list what could cause that mm.free_work is executed at the same time as intel_runtime_pm_driver_release() causing raw-wakerefs warning. So here only calling i915_gem_suspend() and by consequence i915_gem_drain_freed_objects() only after display is down making sure all display gem objecs are freed when intel_runtime_pm_driver_release() is executed.

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.
