With the above being open coded the _ms feels not right.
I would expect the TIME_MIN to be in MS from the start
(and for the consistency's sake with the below) and having
all this to be written like

	ret = bu27034_get_int_time(data);
	if (ret < 0)
		wait_ms = _MS_MIN;
	else
		wait_ms = ret / USEC_PER_MSEC;
