cassini/sungem: limit reaches -1, but 0 tested
while (limit--) if (test()) break; if (limit <= 0) goto test_failed; In the last iteration, limit is decremented after the test to 0. If just thereafter test() succeeds and a break occurs, the goto still occurs because limit is 0. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
