[PATCH-for-5.0 0/3] virtio,vhost-gpu: Release memory returned by malloc() with free()

[Philippe Mathieu-Daudé]

Coverity reported a ALLOC_FREE_MISMATCH in vg_handle_cursor(),
because the memory returned by vu_queue_pop() is allocated with
malloc(). Fix it.

Similar error occurs with virtio. Document and fix.

Philippe Mathieu-Daudé (3):
  vhost-user-gpu: Release memory returned by vu_queue_pop() with free()
  virtio: Document virtqueue_pop()
  virtio-gpu: Release memory returned by virtqueue_pop() with free()
