       This function queries the gate for a subdevice, as set by comedi_set_gate_source. The currently
       configured gate source will be written to *gate_source. The possible values and their corresponding gates
       are driver-dependant. If the subdevice does not support configuring its gates on a per-channel basis,
       then the channel parameter will be ignored.

       This function is only useable on subdevices that provide support for the INSN_CONFIG_GET_GATE_SRC
       configuration instruction.
