[PATCH 0/9] staging: comedi: remove some async command cruft

[H Hartley Sweeten]

The comedi core always calls the subdevice (*do_cmdtest) to validata the
async command before it calls the (*do_cmd) to actually execute the command.

Since the (*do_cmdtest) has already validataed the command, any duplicate
tests in the (*do_cmd) are unnecessary. Remove them.

Also, the cb_das16_cs driver has a (*do_cmdtest) but it's (*do_cmd) just
returns -EINVAL and the interrupt handler does nothing. Remove the async
command support from this driver.
