Check for watchdog_ops structures that are only stored in the ops field of a watchdog_device structure. This field is declared const, so watchdog_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 watchdog_ops i@p = { ... }; @ok@ identifier r.i; struct watchdog_device e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct watchdog_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct watchdog_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/watchdog/bcm7038_wdt.c | 2 +- drivers/watchdog/cadence_wdt.c | 2 +- drivers/watchdog/kempld_wdt.c | 2 +- drivers/watchdog/rn5t618_wdt.c | 2 +- drivers/watchdog/softdog.c | 2 +- drivers/watchdog/w83627hf_wdt.c | 2 +- 6 files changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/watchdog/bcm7038_wdt.c b/drivers/watchdog/bcm7038_wdt.c index 4245b65..e238df4 100644 --- a/drivers/watchdog/bcm7038_wdt.c +++ b/drivers/watchdog/bcm7038_wdt.c @@ -107,7 +107,7 @@ static struct watchdog_info bcm7038_wdt_info = { WDIOF_MAGICCLOSE }; -static struct watchdog_ops bcm7038_wdt_ops = { +static const struct watchdog_ops bcm7038_wdt_ops = { .owner = THIS_MODULE, .start = bcm7038_wdt_start, .stop = bcm7038_wdt_stop, diff --git a/drivers/watchdog/cadence_wdt.c b/drivers/watchdog/cadence_wdt.c index 4dda902..a4e05e43 100644 --- a/drivers/watchdog/cadence_wdt.c +++ b/drivers/watchdog/cadence_wdt.c @@ -269,7 +269,7 @@ static struct watchdog_info cdns_wdt_info = { }; /* Watchdog Core Ops */ -static struct watchdog_ops cdns_wdt_ops = { +static const struct watchdog_ops cdns_wdt_ops = { .owner = THIS_MODULE, .start = cdns_wdt_start, .stop = cdns_wdt_stop, diff --git a/drivers/watchdog/kempld_wdt.c b/drivers/watchdog/kempld_wdt.c index 5bf931c..8e302d0 100644 --- a/drivers/watchdog/kempld_wdt.c +++ b/drivers/watchdog/kempld_wdt.c @@ -430,7 +430,7 @@ static struct watchdog_info kempld_wdt_info = { WDIOF_PRETIMEOUT }; -static struct watchdog_ops kempld_wdt_ops = { +static const struct watchdog_ops kempld_wdt_ops = { .owner = THIS_MODULE, .start = kempld_wdt_start, .stop = kempld_wdt_stop, diff --git a/drivers/watchdog/rn5t618_wdt.c b/drivers/watchdog/rn5t618_wdt.c index d1c1227..0805ee2 100644 --- a/drivers/watchdog/rn5t618_wdt.c +++ b/drivers/watchdog/rn5t618_wdt.c @@ -136,7 +136,7 @@ static struct watchdog_info rn5t618_wdt_info = { .identity = DRIVER_NAME, }; -static struct watchdog_ops rn5t618_wdt_ops = { +static const struct watchdog_ops rn5t618_wdt_ops = { .owner = THIS_MODULE, .start = rn5t618_wdt_start, .stop = rn5t618_wdt_stop, diff --git a/drivers/watchdog/softdog.c b/drivers/watchdog/softdog.c index b067edf..1ae469e 100644 --- a/drivers/watchdog/softdog.c +++ b/drivers/watchdog/softdog.c @@ -92,7 +92,7 @@ static struct watchdog_info softdog_info = { .options = WDIOF_SETTIMEOUT | WDIOF_KEEPALIVEPING | WDIOF_MAGICCLOSE, }; -static struct watchdog_ops softdog_ops = { +static const struct watchdog_ops softdog_ops = { .owner = THIS_MODULE, .start = softdog_ping, .stop = softdog_stop, diff --git a/drivers/watchdog/w83627hf_wdt.c b/drivers/watchdog/w83627hf_wdt.c index 09e8003..ef2ecaf 100644 --- a/drivers/watchdog/w83627hf_wdt.c +++ b/drivers/watchdog/w83627hf_wdt.c @@ -302,7 +302,7 @@ static struct watchdog_info wdt_info = { .identity = "W83627HF Watchdog", }; -static struct watchdog_ops wdt_ops = { +static const struct watchdog_ops wdt_ops = { .owner = THIS_MODULE, .start = wdt_start, .stop = wdt_stop, -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
