path.
This was obviously not intended, so let's just initialize this to
zero.
Not that versed in virgl to know if one should initialize to 0 or 1.
The way I read the code, any value that isn't -1 will do, as that
avoids us from going down the error-path.
In either case please use the following tag.
Should help with picking this fix to the right stable branches.
Fixes: a8987b88ff1 ("virgl: add driver for virtio-gpu 3D (v2)")
Thanks, fixed locally.
