Description
In the Linux kernel, the following vulnerability has been resolved:
caif_virtio: fix wrong pointer check in cfv_probe()
del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked
for NULL before calling it, not cfv->vdev. Also the current implementation
is redundant because the pointer cfv->vdev is dereferenced before it is
checked for NULL.
Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before
calling del_vqs().
