dwc_eth_qos: constify net_device_ops structures
Check for net_device_ops structures that are only stored in the netdev_ops
field of a net_device structure. This field is declared const, so
net_device_ops structures that have this property can be declared as const
also.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct net_device_ops i@p = { ... };
@ok@
identifier r.i;
struct net_device e;
position p;
@@
e.netdev_ops = &i@p;
@bad@
position p != {r.p,ok.p};
identifier r.i;
struct net_device_ops e;
