staging: comedi: quatech_daqp_cs: avoid calculating pacer divisor multiple times

Browse source

The pacer will either be used to trigger each conversion or to start each
scan. Modify the (*do_cmdtest) so that one one divisor calculation is needed.
Save the divisor value in the private data so that the (*do_cmd) does not
have to do the calculation again.
