If I remember correctly that was the reason we have the "if (r != 
-ENOENT)" and "if (ring->ring_size)" checks in the code. E.g. if VCE 
isn't supported ring->ring_size is zero and vce_v1_0_init return -ENOENT.

So when we make the check implicit I think we should at least remove the 
-ENOENT check.

Regards,
Christian.
