/**

 * struct comedi_lrange - Describes a COMEDI range table

 * @length: Number of entries in the range table.

 * @range: Array of &struct comedi_krange, one for each range.

 *

 * Each element of @range[] describes the minimum and maximum physical range

 * range and the type of units.  Typically, the type of unit is %UNIT_volt

 * (i.e. volts) and the minimum and maximum are in millionths of a volt.

 * There may also be a flag that indicates the minimum and maximum are merely

 * scale factors for an unknown, external reference.
