net: xilinx: constify net_device_ops structure
Declare net_device_ops structure as const as it is 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; File size before: text data bss dec hex filename 6201 744 0 6945 1b21 ethernet/xilinx/xilinx_emaclite.o File size after: text data bss dec hex filename 6745 192 0 6937 1b19 ethernet/xilinx/xilinx_emaclite.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: David S.
