Staging: iio: ad7816: constify attribute_group structures
Check for attribute_group structures that are only stored in the event_attrs filed of iio_info structure. As the event_attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant. Done using coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct attribute_group i@p = {...}; @ok1@ identifier r1.i; position p; struct iio_info x; @@ x.event_attrs=&i@p; @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct attribute_group i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct attribute_group i; File size before: text data bss dec hex filename 3295 768 0 4063 fdf drivers/staging/iio/adc/ad7816.o File size after: text data bss dec hex filename 3359 736 0 4095 fff drivers/staging/iio/adc/ad7816.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
