Staging: iio: ad7150: 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;
