staging: comedi: usbduxfast: chanlist check is Step 5 of (*do_cmdtest) The channel list should be checked in Step 5 of the (*do_cmdtest) not as part of the (*do_cmd). Factor the check out of usbduxfast_ai_cmd(). Tidy up the factored out code. The channel number 'i' will never be greater than NUMCHANNELS due to the subdevice setup and the checks done in the code. The up/down of the semaphore is also not needed because the (*do_cmdtest) never actually tries to access the hardware.
