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/)
// <smpl>
@r disable optional_qualifier@
identifier i;
position p;

static struct iio_info i@p = { ... };
@ok@

struct iio_dev e;
position p;
@@
e.info = &i@p;
@bad@
position p != {r.p,ok.p};
identifier r.i;
struct iio_info e;
