I did not realize this initially, but this bug can cause more serious problem
than just a memory leak. In the case that kzalloc fails right from the
beginning with i=0; then in the while loop, "i" will wrap around and the code
will access priv->apTD0Rings[4294967295] which is obviously not good.

Best regards,
Nam
