From 7504dfc9e935e3422d5187f8e813da5758976e6d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 16 Sep 2016 12:55:24 +0200 Subject: [PATCH] iio: common: ssp_sensors: accel: constify iio_info structures Check for iio_info structures that are only stored in the info field of a iio_dev structure. This field is declared const, so iio_info 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 iio_info i@p = { ... }; @ok@ identifier r.i; struct iio_dev e; position p; @@ e.info = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct iio_info e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct iio_info i = { ... }; // The result of size on this file before the change is: text data bss dec hex filename 1265 344 0 1609 649 drivers/iio/accel/ssp_accel_sensor.o and after the change it is: text data bss dec hex filename 1425 192 0 1617 651 drivers/iio/accel/ssp_accel_sensor.o Signed-off-by: Julia Lawall Signed-off-by: Jonathan Cameron --- drivers/iio/accel/ssp_accel_sensor.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/accel/ssp_accel_sensor.c b/drivers/iio/accel/ssp_accel_sensor.c index 4ae05fce9f24..31db00970fa0 100644 --- a/drivers/iio/accel/ssp_accel_sensor.c +++ b/drivers/iio/accel/ssp_accel_sensor.c @@ -74,7 +74,7 @@ static int ssp_accel_write_raw(struct iio_dev *indio_dev, return -EINVAL; } -static struct iio_info ssp_accel_iio_info = { +static const struct iio_info ssp_accel_iio_info = { .read_raw = &ssp_accel_read_raw, .write_raw = &ssp_accel_write_raw, }; -- 2.39.5
