    drivers/net/r6040: fix obvious problems (but more remain)
    
    - checkpatch fixes
    
    - fix bogus and uninitialized return codes in r6040_start_xmit()
    
    - netdev_get_settings() fix obvious locking bug flagged by compiler warning
    
    - set DMA consistent mask
    
    - remove unnecessary setting of dev->base_addr
