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: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct ethtool_ops i@p = { ... }; @ok1@ identifier r.i; struct net_device e; position p; @@ e.ethtool_ops = &i@p; @ok2@ identifier r.i; expression e; position p; @@ netdev_set_default_ethtool_ops(e, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct ethtool_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/net/ethernet/hisilicon/hip04_eth.c | 2 +- drivers/net/ethernet/hisilicon/hisi_femac.c | 2 +- drivers/net/ethernet/hisilicon/hix5hd2_gmac.c | 2 +- drivers/net/ethernet/hisilicon/hns/hns_ethtool.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/net/ethernet/hisilicon/hip04_eth.c b/drivers/net/ethernet/hisilicon/hip04_eth.c index 0c4afe9..a90ab40 100644 --- a/drivers/net/ethernet/hisilicon/hip04_eth.c +++ b/drivers/net/ethernet/hisilicon/hip04_eth.c @@ -755,7 +755,7 @@ static void hip04_get_drvinfo(struct net_device *netdev, strlcpy(drvinfo->version, DRV_VERSION, sizeof(drvinfo->version)); } -static struct ethtool_ops hip04_ethtool_ops = { +static const struct ethtool_ops hip04_ethtool_ops = { .get_coalesce = hip04_get_coalesce, .set_coalesce = hip04_set_coalesce, .get_drvinfo = hip04_get_drvinfo, diff --git a/drivers/net/ethernet/hisilicon/hisi_femac.c b/drivers/net/ethernet/hisilicon/hisi_femac.c index b5d7ad0..ca68e22 100644 --- a/drivers/net/ethernet/hisilicon/hisi_femac.c +++ b/drivers/net/ethernet/hisilicon/hisi_femac.c @@ -699,7 +699,7 @@ static int hisi_femac_net_ioctl(struct net_device *dev, return phy_mii_ioctl(dev->phydev, ifreq, cmd); } -static struct ethtool_ops hisi_femac_ethtools_ops = { +static const struct ethtool_ops hisi_femac_ethtools_ops = { .get_link = ethtool_op_get_link, .get_link_ksettings = phy_ethtool_get_link_ksettings, .set_link_ksettings = phy_ethtool_set_link_ksettings, diff --git a/drivers/net/ethernet/hisilicon/hix5hd2_gmac.c b/drivers/net/ethernet/hisilicon/hix5hd2_gmac.c index 275618b..e69a6be 100644 --- a/drivers/net/ethernet/hisilicon/hix5hd2_gmac.c +++ b/drivers/net/ethernet/hisilicon/hix5hd2_gmac.c @@ -750,7 +750,7 @@ static const struct net_device_ops hix5hd2_netdev_ops = { .ndo_set_mac_address = hix5hd2_net_set_mac_address, }; -static struct ethtool_ops hix5hd2_ethtools_ops = { +static const struct ethtool_ops hix5hd2_ethtools_ops = { .get_link = ethtool_op_get_link, .get_link_ksettings = phy_ethtool_get_link_ksettings, .set_link_ksettings = phy_ethtool_set_link_ksettings, diff --git a/drivers/net/ethernet/hisilicon/hns/hns_ethtool.c b/drivers/net/ethernet/hisilicon/hns/hns_ethtool.c index ab33487..5eb3245 100644 --- a/drivers/net/ethernet/hisilicon/hns/hns_ethtool.c +++ b/drivers/net/ethernet/hisilicon/hns/hns_ethtool.c @@ -1264,7 +1264,7 @@ static int hns_get_rxnfc(struct net_device *netdev, return 0; } -static struct ethtool_ops hns_ethtool_ops = { +static const struct ethtool_ops hns_ethtool_ops = { .get_drvinfo = hns_nic_get_drvinfo, .get_link = hns_nic_get_link, .get_settings = hns_nic_get_settings, -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
