This looks dubious. You don't need to check ring_mask here as that will
be implicit in whatever we test for completeness. ring->name is set at
the start of initialisation and is not cleaned upon error. A better
choice is ring->obj, which we already check in
intel_cleanup_ring_buffer.
So this becomes:
cleanup:
for_each_ring(ring, dev_priv, i)
