Chris Wilson d4de753526 drm/i915: Unwind failure on pinning the gen7 ppgtt
If we fail to pin the ggtt vma slot for the ppgtt page tables, we need
to unwind the locals before reporting the error. Or else on subsequent
attempts to bind the page tables into the ggtt, we will already believe
that the vma has been pinned and continue on blithely. If something else
should happen to be at that location, choas ensues.

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.
