Subject: [Qemu-devel] [PULL 4/5] virtio-gpu: pass down VirtIOGPU pointer to a bunch of functions
Date: Mon, 3 Sep 2018 08:57:44 +0200 [thread overview]
Message-ID: <20180903065745.23055-5-kraxel@redhat.com> (raw)
In-Reply-To: <20180903065745.23055-1-kraxel@redhat.com>
No functional change, just preparation for a followup patch
which needs a VirtIOGPU pointer.
