The comedi subsystem only requires the drivers to support interrupts if one or more of the subdevices support async commands. Since this is optional: 1) don't fail the attach if the irq is not available 2) only hookup the async command support if the irq is available 3) remove any async command init from subdevices that don't need it 4) remove any unnecessary sanity checks in the async command functions Make use of the comedi_device 'read_subdev' and 'write_subdev' pointers instead of accessing the dev->subdevices array directly with "magic" numbers to the correct subdevice. Also, remove any unnecessary debug noise associated with the irq requests.
