As part of our GEM initialisation now, we send a request to the hardware in order to record the initial GPU state. This coupled with deferred idle workers, makes aborting on error tricky. We already have the mechanism in place to wait on the GPU and cancel all the deferred workers for suspend, so let's reuse it during the error teardown. It is already used in places for later init error handling, but doing so at this point is slightly ugly due to the mutex dance (it's ok, the module load is still single threaded).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
