While manual code reviewing, I found some error in ezchip driver.
Two of them looks very dangerous:
  1. use-after-free in nps_enet_remove
      Accessing netdev private data after free_netdev()

  2. wrong error handling of platform_get_irq()
      It can cause passing negative irq to request_irq()

Also, in 2nd patch I removed redundant check to increase execution
speed and make code more straightforward.
