These structures are only used to copy into other structures, so declare them as const. 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 gpio_chip i at p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i at p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e at i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... }; // </smpl> Signed-off-by: Julia Lawall <redacted> --- drivers/gpio/gpio-arizona.c | 2 +- drivers/gpio/gpio-bcm-kona.c | 2 +- drivers/gpio/gpio-da9052.c | 2 +- drivers/gpio/gpio-da9055.c | 2 +- drivers/gpio/gpio-it87.c | 2 +- drivers/gpio/gpio-lp873x.c | 2 +- drivers/gpio/gpio-lpc18xx.c | 2 +- drivers/gpio/gpio-pisosr.c | 2 +- drivers/gpio/gpio-sch.c | 2 +- drivers/gpio/gpio-stmpe.c | 2 +- drivers/gpio/gpio-tc3589x.c | 2 +- drivers/gpio/gpio-tpic2810.c | 2 +- drivers/gpio/gpio-tps65086.c | 2 +- drivers/gpio/gpio-tps65218.c | 2 +- drivers/gpio/gpio-tps65912.c | 2 +- drivers/gpio/gpio-ts4900.c | 2 +- drivers/gpio/gpio-twl4030.c | 2 +- drivers/gpio/gpio-wm831x.c | 2 +- drivers/gpio/gpio-wm8350.c | 2 +- drivers/gpio/gpio-wm8994.c | 2 +- 20 files changed, 20 insertions(+), 20 deletions(-)diff --git a/drivers/gpio/gpio-lpc18xx.c b/drivers/gpio/gpio-lpc18xx.c index 98832c9..f12e02e 100644 --- a/drivers/gpio/gpio-lpc18xx.c +++ b/drivers/gpio/gpio-lpc18xx.c@@ -78,7 +78,7 @@ static int lpc18xx_gpio_direction_output(struct gpio_chip *chip, return lpc18xx_gpio_direction(chip, offset, true); } -static struct gpio_chip lpc18xx_chip = { +static const struct gpio_chip lpc18xx_chip = { .label = "lpc18xx/43xx-gpio", .request = gpiochip_generic_request, .free = gpiochip_generic_free,
