    iio: adc: hx711: constify attribute_group structures · 4214dc18
    simran singhal authored
    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};
