From 85f15cfc213da88d9eb01c943be454328b104f3c Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 19:35:26 +0200 Subject: watchdog: constify watchdog_ops structures 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/) // @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 = { ... }; // Signed-off-by: Julia Lawall Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck --- 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(-) (limited to 'drivers/watchdog') diff --git a/drivers/watchdog/bcm7038_wdt.c b/drivers/watchdog/bcm7038_wdt.c index 4245b65d645c..e238df4d75a2 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 0fd267eb9342..98acef72334d 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 5bf931ce1353..8e302d0e346c 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 d1c12278cb6a..0805ee2acd7a 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 b067edf246df..1ae469e94045 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 09e8003039dc..ef2ecaf53a14 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, -- cgit v1.2.3
