From dda3e26501b153757ad0adbb9f2360612e1edf24 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 31 Aug 2016 09:30:43 +0200 Subject: [PATCH] staging: slicoss: constify ethtool_ops structures 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/) // @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 = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman --- drivers/staging/slicoss/slicoss.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/slicoss/slicoss.c b/drivers/staging/slicoss/slicoss.c index 7834bda2bbff..21280a3a31bb 100644 --- a/drivers/staging/slicoss/slicoss.c +++ b/drivers/staging/slicoss/slicoss.c @@ -124,7 +124,7 @@ static const struct pci_device_id slic_pci_tbl[] = { { 0 } }; -static struct ethtool_ops slic_ethtool_ops; +static const struct ethtool_ops slic_ethtool_ops; MODULE_DEVICE_TABLE(pci, slic_pci_tbl); @@ -3128,7 +3128,7 @@ static void __exit slic_module_cleanup(void) pci_unregister_driver(&slic_driver); } -static struct ethtool_ops slic_ethtool_ops = { +static const struct ethtool_ops slic_ethtool_ops = { .get_coalesce = slic_get_coalesce, .set_coalesce = slic_set_coalesce }; -- 2.39.5
