From 7123f253f02b7370ad25d9047fd91a5ef6ae551f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 19:35:25 +0200 Subject: [PATCH] watchdog: tegra: 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 Acked-by: Thierry Reding Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck --- drivers/watchdog/tegra_wdt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/watchdog/tegra_wdt.c b/drivers/watchdog/tegra_wdt.c index 9ec57608da82..2d53c3f9394f 100644 --- a/drivers/watchdog/tegra_wdt.c +++ b/drivers/watchdog/tegra_wdt.c @@ -178,7 +178,7 @@ static const struct watchdog_info tegra_wdt_info = { .identity = "Tegra Watchdog", }; -static struct watchdog_ops tegra_wdt_ops = { +static const struct watchdog_ops tegra_wdt_ops = { .owner = THIS_MODULE, .start = tegra_wdt_start, .stop = tegra_wdt_stop, -- 2.39.2
