From 323edb2e27e8e02b0ce25e7caa8288a90a438b99 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 3 Aug 2017 23:21:31 +0200 Subject: [PATCH] watchdog: constify watchdog_ops and watchdog_info structures These watchdog_ops and watchdog_info structures are only stored in the ops and info fields of a watchdog_device structure, respectively, which are const. Thus make the watchdog_ops and watchdog_info structures const as well. Done with the help of Coccinelle. The rules for the watchdog_ops case are as follows: // @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: Linus Walleij Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck --- drivers/watchdog/diag288_wdt.c | 2 +- drivers/watchdog/mt7621_wdt.c | 2 +- drivers/watchdog/rt2880_wdt.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/watchdog/diag288_wdt.c b/drivers/watchdog/diag288_wdt.c index 6f591084bb7a..806a04a676b7 100644 --- a/drivers/watchdog/diag288_wdt.c +++ b/drivers/watchdog/diag288_wdt.c @@ -213,7 +213,7 @@ static const struct watchdog_ops wdt_ops = { .set_timeout = wdt_set_timeout, }; -static struct watchdog_info wdt_info = { +static const struct watchdog_info wdt_info = { .options = WDIOF_SETTIMEOUT | WDIOF_KEEPALIVEPING | WDIOF_MAGICCLOSE, .firmware_version = 0, .identity = "z Watchdog", diff --git a/drivers/watchdog/mt7621_wdt.c b/drivers/watchdog/mt7621_wdt.c index f6f4c1bf24c9..db38f8017218 100644 --- a/drivers/watchdog/mt7621_wdt.c +++ b/drivers/watchdog/mt7621_wdt.c @@ -105,7 +105,7 @@ static int mt7621_wdt_bootcause(void) return 0; } -static struct watchdog_info mt7621_wdt_info = { +static const struct watchdog_info mt7621_wdt_info = { .identity = "Mediatek Watchdog", .options = WDIOF_SETTIMEOUT | WDIOF_KEEPALIVEPING | WDIOF_MAGICCLOSE, }; diff --git a/drivers/watchdog/rt2880_wdt.c b/drivers/watchdog/rt2880_wdt.c index 0d481a63cab1..98967f0a7d10 100644 --- a/drivers/watchdog/rt2880_wdt.c +++ b/drivers/watchdog/rt2880_wdt.c @@ -119,7 +119,7 @@ static int rt288x_wdt_bootcause(void) return 0; } -static struct watchdog_info rt288x_wdt_info = { +static const struct watchdog_info rt288x_wdt_info = { .identity = "Ralink Watchdog", .options = WDIOF_SETTIMEOUT | WDIOF_KEEPALIVEPING | WDIOF_MAGICCLOSE, };
