drm/virtio: fix resource id creation race

2020-03-12T06:18:39+00:00

commit fbb30168c7395b9cfeb9e6f7b0c0bca854a6552d upstream. The previous code was not thread safe and caused undefined behavior from spurious duplicate resource IDs. In this patch, an atomic_t is used instead. We no longer see any duplicate IDs in tests with this change.
