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; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct net_device_ops i = { ... }; // </smpl> The result of size on this file before the change is: text data bss dec hex filename 21623 1316 40 22979 59c3 drivers/net/ethernet/synopsys/dwc_eth_qos.o and after the change it is: text data bss dec hex filename 22199 724 40 22963 59b3 drivers/net/ethernet/synopsys/dwc_eth_qos.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.
