[PATCH] net: moxa: constify net_device_ops structures

[Bhumika Goyal]

Declare net_device_ops structures as const as they are only stored in
the netdev_ops field of a net_device structure. This field is of type
const, so net_device_ops structures having same properties can be made
const too.
Done using Coccinelle:

@r1 disable optional_qualifier@
identifier i;
position p;
@@
static struct net_device_ops i@p={...};

@ok1@
identifier r1.i;
position p;
struct net_device ndev;
@@
ndev.netdev_ops=&i@p

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;
@@
i@p

@depends on !bad disable optional_qualifier@
identifier r1.i;

+const
struct net_device_ops i;
