Commit 39a2bd34c933 ("drm/i915: Use the vma resource as argument for gtt
binding / unbinding") introduced a regression that due to the vma resource
tracking of the binding state, dpt ptes were not correctly repopulated.
Fix this by clearing the vma resource state before repopulating.
The state will subsequently be restored by the bind_vma operation.

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.
