    dwc_eth_qos: constify ethtool_ops structures · 777065e5
    Julia Lawall authored
    Check for ethtool_ops structures that are only stored in the ethtool_ops
    field of a net_device structure or passed as the second argument to
    netdev_set_default_ethtool_ops.  These contexts are declared const, so
    ethtool_ops structures that have these properties can be declared as const
    also.
    
    The semantic patch that makes this change is as follows:
