Subject: [PATCH 13/34] drm/i915/gvt: devirtualize ->{read,write}_gpa
Date:   Mon, 11 Apr 2022 16:13:42 +0200
Message-Id: <20220411141403.86980-14-hch@lst.de>
In-Reply-To: <20220411141403.86980-1-hch@lst.de>

Precedence: bulk

Just call the VFIO functions directly instead of through the method
table.
