| |
Check for attribute_group structures that are only stored in the attrs filed of iio_info structure. As the 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.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;
