From 52ceb7731e7c23101a26e91aad81ae30de87b10d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 16 Sep 2016 12:55:25 +0200 Subject: [PATCH] iio: adc: men_z188_adc: 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 1529 312 0 1841 731 drivers/iio/adc/men_z188_adc.o and after the change it is: text data bss dec hex filename 1689 168 0 1857 741 drivers/iio/adc/men_z188_adc.o Signed-off-by: Julia Lawall Signed-off-by: Jonathan Cameron --- drivers/iio/adc/men_z188_adc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/adc/men_z188_adc.c b/drivers/iio/adc/men_z188_adc.c index d095efe1ba14..8f3606de4eaf 100644 --- a/drivers/iio/adc/men_z188_adc.c +++ b/drivers/iio/adc/men_z188_adc.c @@ -78,7 +78,7 @@ static int z188_iio_read_raw(struct iio_dev *iio_dev, return ret; } -static struct iio_info z188_adc_info = { +static const struct iio_info z188_adc_info = { .read_raw = &z188_iio_read_raw, .driver_module = THIS_MODULE, };
