Subject: [PATCH 10/21] drm/i915/gvt: remove vgpu->handle
Date:   Wed, 21 Jul 2021 17:53:44 +0200
Message-Id: <20210721155355.173183-11-hch@lst.de>
In-Reply-To: <20210721155355.173183-1-hch@lst.de>
References: <20210721155355.173183-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Always pass the actual vgpu structure instead of encoding it as a
"handle" and add a bool flag to denote if a VGPU is attached.
