checkpatch suspected false positive

["Tobin C. Harding" <me@tobin.cc>]

Checkpatch may be giving a false positive of type CONST_STRUCT when
parsing files in drivers/staging/comedi/drivers.

$ pwd

$ cd drivers/staging/comedi/drivers

$ checkpatch --terse --show-types *.c | grep CONST_STRUCT

snippet from das16.c

/* get any user-defined input range */
if (pg_type == das16_pg_none && (min || max)) {
	struct comedi_lrange *lrange;
	struct comedi_krange *krange;

	/* allocate single-range range table */
	lrange = comedi_alloc_spriv(s, sizeof(*lrange) + sizeof(*krange));
	if (!lrange)
		return &range_unknown;

	/* initialize ai range */
	lrange->length = 1;
	krange = lrange->range;
	krange->min = min;
	krange->max = max;
	krange->flags = UNIT_volt;

	return lrange;
}

>From snippet it may be seen that struct comedi_lrange *lrange should
not be const.

In the event that I am in the wrong and checkpatch is correct please
feel free to bluntly correct me.

thanks,
Tobin.
