    Staging: iio: addac: constify attribute_group structures · f0c81616
    Bhumika Goyal authored
    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@
